Q620E high strength alloy steel
Q620E high strength sheet metal is tempered high-strength steel plate, where Q represents the yield strength of steel "yield" word hanyu pinyin letters; 620 is the normative rules of the small yield strength value, the unit is MPa; E is the quality level symbol.
Q620E high strength structural steel has good welding performance, can be conventional welding, arc welding, gas shielded welding and other welding processes, and at the same time can meet the performance requirements of welded joints.
Meanwhile, our Q620E high strength plate can provide customised size, cutting, welding, punching and other processing services according to your end-use requirements of Q620E high strength steel sheet products.
