40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel q295nh steel is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15~40mm during oil quenching. When the hardness is HB174~229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

Due to its high processing efficiency and good quality, it has gradually replaced the traditional processing technology and has become the mainstream equipment for sheet metal processing.
The Q295NH steel plate is heated to about 500~600, retained for a period of time, and then cooled to 200~300 with the furnace, and then air-cooled. Its purpose is to remove the internal stress of Q295NH steel plate, stabilize the size, and reduce deformation. The important role of Q295NH weathering steel plate annealing q295nh steel (1) reduce the hardness of Q295NH weathering steel plate, improve the plasticity, in order to facilitate cutting and cold deformation processing. (2) refine the grain, uniform the structure and composition of steel, improve the performance of Q295NH weathering steel plate or prepare for the subsequent heat treatment.

After adding trace elements such as phosphorus, copper, chromium and nickel into GB/T 4171 Q295NH weathering steel plates, a protective film with dense and strong adhesion is formed on the surface of Q295NH steel, which prevents the rust from spreading and developing, and protects the underlying matrix of rust layer to slow down its corrosion rate, which greatly improve the corrosion q295nh steel Corten A weathering steel Corten A Weathering Steel ASTM Corten A steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The steel grade CortenA is according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa.Corten-A steel was first used in buildings in 1958 because it has anti-corrosion q295nh steel China GB/T 4171 Q295NH atmospheric corrosion resistant steel q295nh steel 0086-371-86151827; [email protected] q295nh steel; Contact With Us: HOME; PRODUCT
High strength weathering steel has been used in bridge engineering.It can also be used in the floor board,containers, power plant chimneys, railway engineering and other outdoor steel, such as large outdoor sculpture steel. MOQ: 3pc: Shipment Time: Within 15-20 workdays after receiving deposit or L/C: Export Packing: Waterproof paper, and steel q295nh steel COR-TEN / Weathering Steel Plate Corten steel plate or sheet, is a type of alloy steel plate. When uncoated exposed to the weather, Corten steel plates would rust and the rust forms a protective coating on the external surface which slows the rate of future corrosion, thus to prevent the steel material from acidic environments. Buy Weathering Steel-Corten A|A709|A242M|A588 From AGICO The applicable equivalent ASTM specifications for weathering steel are ASTM A588, ASTM A242, ASTM A606-4, ASTM A847 and ASTM A709-50W, other standards JIS G3125, JIS G3114, EN10025 and GB/T4171.
