We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
Type 304 and Type 316 stainless steels are unaffected weak bases similar to ammonium hydroxide, even in high concentrations and at excessive temperatures. The identical grades exposed to stronger bases similar to sodium hydroxide at high concentrations and high temperatures will likely expertise some etching and cracking. Increasing chromium and nickel contents provide elevated resistance. The addition of nitrogen additionally improves resistance to pitting corrosion and will increase mechanical energy.
What does ASTM mean?
Austenitic stainless steels generally provide the most corrosion resistance because of their high amounts of chromium. This makes grade 304 an excellent choice when corrosion resistance is important.

Thus, there are numerous grades of stainless steel with various chromium and molybdenum contents to go well with the surroundings the alloy must endure. Due to the addition of molybdenum, grade 316 chrome steel is extra corrosion resistant than related alloys, similar to 304 stainless-steel. This reduces pitting from chemical environments and allows grade 316 chrome steel for use in extremely acidic and caustic environments that may otherwise eat away on the metal. For instance, grade 316 stainless-steel can withstand caustic solutions and corrosive applications such as vapor degreasing or many different elements cleansing processes. Another popular high-performing alloy, grade 304 chrome steel is a durable material in terms of tensile strength, durability, corrosion, and oxidation resistance.
There are over 150 grades of chrome steel, of which fifteen are the most used. Grade ASTM A Stainless Steel is the usual “18/eight” stainless; it is the most versatile and most widely used stainless-steel, obtainable in a wider vary of products, forms and finishes than any other. It has glorious forming and welding traits.
- The minimal 10.5% chromium in stainless steels provides resistance to approximately seven hundred °C (1,300 °F), whereas 16% chromium supplies resistance as much as approximately 1,200 °C (2,200 °F).
- Type 304, the most common grade of stainless steel with 18% chromium, is immune to approximately 870 °C (1,600 °F).
- Stainless steels have a protracted historical past of software in touch with water as a result of their excellent corrosion resistance.
- Other gases, similar to sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, additionally assault stainless steel.

Type 316 metal is an austenitic chromium-nickel chrome steel that accommodates between two and three% molybdenum. The molybdenum content material will increase corrosion resistance, improves resistance to pitting in chloride ion options, and increases energy at excessive temperatures. The time period ‘corrosion resistant metal’ is used when the alloy has less than the 12% minimal of chromium, for example in the aviation industry. There are completely different grades and floor finishes of stainless steel, depending on the place it will be used. Stainless steels have a higher resistance to oxidation (rust) and corrosion in lots of natural and man-made environments; however, it is important to select the correct sort of stainless steel for the use.
Martensitic Stainless grades are a group of stainless alloys made to be be corrosion resistant and harden-in a position (using warmth treating). All martensitic grades are easy chromium steels without nickel. Martensitic grades are mainly used where hardness, strength, and put on resistance are required.
Duplex grades are typically most well-liked due to their corrosion resistance and better energy, permitting a reduction of weight and a long life in maritime environments. The ease of welding largely depends on the type of stainless steel used.
Is 304 stainless steel rust proof?
The alloy has excellent resistance to intergranular corrosion in the as-welded condition. Alloy 304/304L has excellent strength and toughness at cryogenic temperatures. Alloy 304/304L is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding.
Quite generally, Stainless mills provide these stainless grades as twin licensed, corresponding to 304/304L or 316/316L. Ferritic Stainless grades resist corrosion and oxidation, while remaining immune to stress and cracking.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
