1000 width JIS SM490YA plates hot sale

Hull structural steel is divided into general thickness and high-strength steel. General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, JIS SM490YA plates, EH36. In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 2.5, and the carbon equivalent is also strictly required. Our Hull structural steel plates can be supplied with certificates from different classification societies.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the JIS SM490YA plates, alloy steel is very high, it is not easy to break and can be used for a long time.

Tempering the important JIS SM490YA plates welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve JIS SM490YA plates strength, plasticity and toughness.
