Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of a633 grade e ultimate strength service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
a633 grade e ultimate strength, No.45 seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of No.45 seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.
ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 a633 grade e ultimate strength. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: a633 grade e ultimate strength Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: a633 grade e ultimate strength Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than a633 grade e ultimate strength. 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 a633 grade e ultimate strength 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.
