How long will A588 Grade A HIC tested plate last not rust outside?

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A588 Grade A HIC tested plate production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

The carbon and low alloy steel plates are our main products. Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, A588 Grade A HIC tested plate, (S)A572, (S)A573, (S)A633, (S)A709, EN10025-2, EN10025-3, EN10025-4, EN10025-6, JIS G3101, JIS G3106, DIN 17100, DIN 17102, etc. Our typical carbon and low alloy steel grades are (S)A36, (S)A283 grade C, (S)A572 grade 50, S235JR, S355JR, S355J2, SS400, SM570, ST37-2, ST52-3, Q235B, A588 Grade A HIC tested plate, Q345B, etc.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. A588 Grade A HIC tested plate, 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.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, A588 Grade A HIC tested plate has good atmosphere corrosion resistance.
