Established in 2014, Steel Safety Day was set up to reinforce awareness of the five most common causes of safety incidents and to create a safer working environment across the entire steel industry worldwide. By focusing every year on the five causes - moving machinery, working at heights, falling objects, on-site traffic and sa 283 grade d low-alloy high-strength steel process safety incidents - worldsteel intends to set up a continuous improvement process and reiterate its commitment to the safety and health of the people who work in the sa 283 grade d low-alloy high-strength steel industry.
When the sa 283 grade d low-alloy high-strength steel, wear-resistant steel plate is produced, relevant heat treatment must be carried out, and then forging and processing are carried out after preheating. When the wear-resistant steel plate is heat treated, the temperature should be properly controlled. The heating temperature of the wear-resistant steel plate is 810-830 degrees, and the holding time depends on the furnace loading method. Tempering temperature: 320 degrees, sufficient time is necessary, oil cooling after tempering to reduce temper brittleness.
S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. sa 283 grade d low-alloy high-strength steel, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, sa 283 grade d low-alloy high-strength steel.
