At what humidity does SA514 grade E steel material rust?

Based on the SA514 grade E steel material steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of SA514 grade E steel material steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

45Mn carbon structural steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness. It is generally used in the quenched and tempered state, and SA514 grade E steel material can also be used in Used in quenched and tempered or normalized state.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. SA514 grade E steel material, 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.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. SA514 grade E steel material, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

SA514 grade E steel material, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.
