4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. 42crmo4 alloy steel, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. 42crmo4 alloy steel, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.

Our company will accept the product quality objection registration record, pass it to the 42crmo4 alloy steel production unit and relevant departments, and timely coordinate the supervision of product 42crmo4 alloy steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
