In 1045 steel plate, the ‘10’ means a basic carbon steel and ‘45’ designates the approximate carbon content. 1045 steel is included in the ASTM 830 (A830) family of specifications. A830 Grade 1045 hot rolled steel plate can be cut to various shapes, hammer forged and heat treated. 1SA588 grade B carbon steel plate sheet product is mostly used where greater strength is required than lower carbon steels. Welcome to contact us for hot rolled plates stock price.

20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.

The hot rolling method is to heat the SA588 grade B carbon steel plate sheet steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of SA588 grade B carbon steel plate sheet rolling process is usually called semi-finished product production, also called blank production.

ASTM A537 class 1 boiler plate is pressure vessel steel. SA588 grade B carbon steel plate sheet, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.

Both parties shall confirm the SA588 grade B carbon steel plate sheet material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement.
