ZG20SiMn is a low-alloy cast steel with high sensitivity to hydrogen-induced cracking. Due to the thickness of the base material, there is a relatively high level of constraint and susceptibility to cold cracking. Therefore, when selecting welding materials, it is advisable to prioritize the use...
In fact, according to the content of chromium and nickel, it is all 304 stainless steel, and the composition is 18% chromium (Cr) and 8% nickel (Ni), but the main difference is the carbon content.
304L is an ultra-low carbon stainless steel, the carbon content is reduced to below 0.03%, which...
