a537 class 1 chemical composition for machinery manufacturing

Mo alloy boiler steel plate a537 class 1 chemical composition is mainly used for building pressure vessels.The minimum yield strength of SB480M shall be above 275Mpa, and tensile strength of SB480M shall be within 480-620Mpa. For boiler steel plate SB480M with thickness exceeding 38mm shall be normalized when rolling,and belows or equal to 38mm thickness, as rolled is ok. Besides, ultrasonic test is necessary,and high tension, simulated post welded heat treatment shall be chosen by the end users.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. a537 class 1 chemical composition, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

Semi-endless rolling technology has three advantages: the a537 class 1 chemical composition product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

We have a professional production team and high-quality production equipment, and we also have a great a537 class 1 chemical composition advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the a537 class 1 chemical composition production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Both parties shall confirm the a537 class 1 chemical composition material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the a537 class 1 chemical composition steel plant.
