ASTM A 242 GR. 1 steel plate, Corten A chemical composition, A 242 GR. 1 steel plate, under ASTM standard, we can regard A 242 GR. 1 steel plate as Steel Resistant to Atmospherical Corrosion A 242 GR. 1 steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, A 242 GR. 1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of Corten A chemical composition, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than Corten A chemical composition. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel Corten A chemical composition is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
