Prove Your Metal
China United iron and steel limited produce ASTM A36 steel sheets and steel plates. Our main products are ASTM A36 steel plate, ASTM A36 steel coil, ASTM A36 H Beam, ASTM A36 IPN, ASTM A36 UPN, ASTM A36 IPE, ASTM A36 round bar.
This signifies that while most grades must have added alloys that fit between sure percentages, A36 should meet particular mechanical standards. For instance, metal bars and plates must have a minimal yield power of 36,000 pounds per sq. inch. While there are some chemical composition necessities that A36 metal must adhere to, crucial attribute is the yield strength requirement.

These additions flip the material into a low-alloy metal by some definitions, however AISI’s definition of carbon steel allows as much as 1.sixty five% manganese by weight. When carbon steel is heated into the austenite range—after which cooled without any alloy present to keep the austenite shape—the microstructure reverts to the ferrite form. However, if the carbon content is greater than 0.006%, the surplus carbon atoms combine with iron to kind a chemical compound known as iron carbide , also called cementite. Cementite doesn’t happen by itself as a result of a few of the material will stay in ferrite type. Unlike most AISI grades similar to 1018, 1141, or 4140, American Society for Testing and Materials A36 metal is not designated by chemical composition.
ASTM A36 steel low temperature limits
The low carbon also prevents warmth remedy from having much of an impact on A36 metal. A36 steel usually has small quantities of other alloying parts as properly, including manganese, sulfur, phosphorus, and silicon.
- Trace impurities of varied other elements can have a big effect on the quality of the ensuing metal.
- Trace amounts of sulfur particularly make the steel red-short, that is, brittle and crumbly at working temperatures.
- Carbon steels which may successfully endure warmth-therapy have a carbon content material in the range of 0.30–1.70% by weight.
Impurities are burned away and alloying components are added to the molten steel. Once the chemical composition of the A36 metal is achieved, it’s solidified in into an oblong ingot. This means that it is fashioned to its ultimate dimensions in utilizing rollers while the ingot is at an elevated temperature. High carbon metal is first heated above the higher important temperature.
Then it is maintained, cooled to the decrease important temperature, and maintained once again. This process ensures that the material reaches a uniform temperature and microstructure before the subsequent cooling step. Low carbon steels are categorized by having less than 0.3% carbon by weight. This allows A36 metal to be simply machined, welded, and formed, making it extremely helpful as a general-purpose metal.
Both AISI 316 stainless steel and ASTM A36 carbon steel are iron alloys. There are 31 material properties with values for both materials. A36 metal is the grade for one of the most common types of structural steels used at present.
Carbon steels which might efficiently endure heat-remedy have a carbon content material within the range of 0.30–1.70% by weight. Trace impurities of varied other components can have a big effect on the standard of the resulting steel. Trace amounts of sulfur specifically make the metal purple-short, that is, brittle and crumbly at working temperatures. Low-alloy carbon steel, such as A36 grade, contains about 0.05% sulphur and melts round 1,426–1,538 °C (2,599–2,800 °F). Manganese is often added to enhance the hardenability of low-carbon steels.
These alloying elements are added to offer A36 steel its desired chemical and mechanical properties. Since A36 doesn’t contain large amounts of nickel or chromium, it doesn’t have wonderful corrosion resistance.
