What is the difference between Q235A steel and Q235B steel? First, The carbon content of Q235A steel is 0.22%, higher than that of Q235B steel, which is 0.20%. The sulfur content of Q235A steel is 0.050%, higher than that of Q235B steel, which is 0.045%. Second, steel A573 Grade 58, Q235 material belongs to carbon structural steel. The English letters A and B at the back have different meanings. They are impact temperature requirements. Q235A steel is not subject to impact, while Q235B steel is subject to 20 ℃ room temperature impact.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of steel A573 Grade 58, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of steel A573 Grade 58, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.
As for Q460 series low alloy steel, there are three quality Grade C, D, E. steel A573 Grade 58, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
