DIN 1.0501 Steel
As a high-quality carbon structural steel, DIN 1.0501 is defined as an unalloyed steel with a moderate carbon content of 0.35% as per European standards.
DIN 1.0501 steel has appropriate strength, good plasticity and good process performance. Compared with C22 steel, the welding performance is slightly worse, but still acceptable.Normally, C35 steel is used in normalized and quenched and tempered condition.
DIN 1.0501 steel is widely used in the manufacture of various forgings and hot-pressed parts, cold-drawn and upsetting steels, seamless steel pipes, parts in machinery manufacturing, such as crankshafts, rotating shafts, shaft pins, levers, connecting rods, beams, sleeves, wheels Rings, washers, screws, nuts, etc.
