Does Good Stainless Steel Rust on Barbeque Grill Parts?
Why do stainless steel grill parts rust? This is another question we get asked all the time and there are almost as many answers as there are gas BBQ grills. I meet customers who purchase a stainless steel barbecue grill with a lifetime guarantee because they no longer want to buy a new grill every two years. They feel tricked a year alter when the barbeque grill parts are pitting and rusting. There are a lot of answers to this question but most of them are simple and sometimes obvious.
One reason is the quality of the grill parts. We know restaurants and resorts cannot waste time buying a new grill for their kitchen every few years so we assume if we purchase commercial quality items we can get the same level of quality as professionals. Now any cheap, low cost manufacturer can call their product a commercial series or a professional series item and the association is made. Add a few hundred dollars profit to the price and the customer gets tricked. I have seen this in many industries when the terms "commercial" and "professional" get used as the name of a product model rather than a true description of the quality of the product.
Many of these manufacturers will use a low grade stainless steel to further the association with commercial quality. Many of us do not realize there are many different types of stainless steel. We do not understand the differences and we go looking for stainless as symbolic of a well made product. I cannot tell you how often a buyer will walk into my retail store claiming they want a stainless grill. In their mind, they have asked for a particular level of quality using the term "stainless steel". With a few extra questions, they will share their belief that stainless steel will save them the inconvenience of replacing grill parts within the year or buying a whole new grill next year. Stainless steel comes in a variety of prices and qualities, many much lower quality than steel or cast iron.
Look at who makes the grill - not the importer but the actual manufacturer. American manufacturers will document the type of materials used but be cautious of the importer claiming to be a manufacturer. If the manufacturer is providing a warranty, call them and see if a human answers or if the warranty is a sham. When we purchase an American Made stainless steel BBQ grill, we spend a lot more money and have much higher expectations of the product. Contact local dealers and find out if local professionals who repair grills recommend the product.
Commercial products do not say "commercial" on them and restaurants or resorts do not buy their appliances at the gigantic retail exchanges that advertise the lowest price in town. I have clients who purchase a $300. grill and feel they have spent a lot of money. For that BBQ owner the information above regarding different types of stainless steel is applicable. Keep the grill covered and clean it as often as possible.
High quality barbecues will be manufactured by a stainless steel designated as 304. 304 stainless steel is often referred to as 18/8 stainless because of the main chemical additives that make it resilient outdoors. In order to be considered 304 stainless steel not only are iron oxides drained to such a degree that a magnet cannot hold it but nickel and chromium are added during the smelting process in amounts of 8% nickel and 18% chromium.
Chemicals added to stainless steel protect the material in its specific application. A different stainless steel is used for an indoor refrigerator that does not contend with humidity, rain, snow or heat. Outdoor gas barbeque grills use 18 gauge 304 stainless steel because of the nickel and chromium. Nickel is a hardening agent. Nickel is shiny and attractive but its main benefit is as a hardener. When stainless begins to rust it shows up as "pits". When oxidation begins a small rust spot will appear at the weakest parts of the stainless as a pit. Nickel at eight percent in outdoor stainless hardens the surface to resist pitting.
Chromium protects the surface of the stainless steel in the same way that oil protects a cast iron pot. Chromium reacts with oxygen in the atmosphere and creates a barrier at the surface of the stainless steel. Because chromium is inside the material itself, chromium will rebuild the protective coating after stainless is sanded and polished to remove rust spots. Chromium is added during the smelting process so scratching-out rust does not remove the protective effects of chromium.
Mid-range barbeque grills like Weber and Broil King use combinations in manufacturing. While the majority of the stainless steel on these grills is of the 400 designation, the cooking grates, heat shields and gas burners will be made of 304 stainless steel. This is because the inside of the grill gets wiped down less and gets a whole lot messier than the hood.
For the very expensive grill that has a lifetime guarantee against rust, the reason your grill is rusting is grease. I have seen DCS grills over twenty years old without a single pit on the outside of the barbeque but the burners have been replaced six times. On the rare occasion a customer claims the hood is rusting, it is usually not rust but a light discoloration caused by heat. When the grill shows rust, it is the burners, heat shields, rod trays, cooking grates, etc. The grill parts inside the firebox get grease and drippings and carbon discoloration from heat. All of these things combine to coat the stainless and stop the chromium from reacting with oxygen in the atmosphere.
Every year I remove the burners, cooking grids and shields from my marbeque. I clean - really clean - the inside of the firebox and I clean the parts I have removed. I use a stainless steel brush on the end of a drill and a razor blade. It does a great job and the stainless looks great until I cook on it again.
I have not seen a full size barbeque (as opposed to portable units) for under one thousand dollars that used good quality stainless steel as quality materials are more expensive. No one will tell a client that stainless is often a decoration as cheaply applied as paint on lower cost grills. Either accept that you will have to buy a new BBQ grill every two years or start buying replacement grill parts. Next time you buy a barbeque in the same price range, get an aluminum grill that is made in America. Pure aluminum will last forever.
Often, the best tool to fix a problem is education. Once we understand a problem, the solution will show up in our normal actions. Once you know the chromium needs oxygen to protect your stainless steel your regular post-grilling habits may change. The way you wipe down the grill may be directed at the problem instead of just brushing off charred food bits.
Another point to remember is your barbecue grills placement in relation to your pool. Pool chemicals can cause the grill to corrode if in direct contact with high quality stainless steel. However, the stainless steel can also be damaged just by closeness to the pool or stored pool chemicals. Pool chemicals merge with oxygen in the air. Near the pool, a shortage of oxygen atoms can cause the same effect as covering the stainless steel with grease. Chromium becomes unable to react with the oxygen in the air.
Use your barbeque often and enjoy the value it brings to your backyard. Also the heat lessens mess. After cooking, burn the grill on high or ten to twelve minutes to dry it out and then scrape the stainless. Once or twice a year, take it apart or call a professional. A properly maintained gas grill should last forever.
Military meps issue i need an answer? Sorry to ask again added details ?
I am going to meps weds an i have these scars on my arm from a gas remote control air plane the plane ran up my arm while the aluminum blades where spining an cut me up i didnt go to the hospital i jus bandage them up now what will meps do with no medical record i mean its the truth i dont lie an joining the army has been my dream what happens if they dont believe me i am willing to serve my country proudly i will plead to them if i have

You do not plead, you do not cower, you do not get angry or abusive,
You say, Sir, or Ma'am I had an accident when I was younger and did not have health insurance. I took the best care of my arm that I could at that time, Sir.
You keep your mouth shut..until you are asked a direct question, and you answer as short as possible with as few of words as possible and be assertive about your answer.
You keep your cool, and you say it was an accident that went unattended. and leave it at that. No explanations, apologies, more words than that unless asked.
Say less than more.
