marine grade AH32 steel plate price per kg

Post-welding heat treatment, post-welding heat treatment can help the overflow of hydrogen diffused in the marine grade AH32 steel plate weld metal, effectively reduce the hydrogen content in the weld metal.It can reduce the tendency of cold crack in weld and prevent lamellar tear of thick plate base metal.

When cutting parts with gas, the verticality of the marine grade AH32 steel plate section of the parts should not be greater than 15% of the thickness of the parts. There can be rounded corners at the sharp corners, but the radius should not be greater than 2.5mm. The concave and convex points at the edges of the parts should not exceed 1.5mm. If the parts are cut by hand, the verticality of the section shall not be greater than 15% of the thickness of the parts. If the parts are cut underwater, the verticality of the section should not be greater than 10% of the thickness of the parts.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as marine grade AH32 steel plate. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
