SM400B carbon steel plate sheet for boilers and pressure vessels

ASTM A633 standard covers four grades A, C, D, and E normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. SM400B carbon steel plate sheet, A633 Grade A structural steel provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, SM400B carbon steel plate sheet seamless steel pipes for ships and petroleum cracking SM400B carbon steel plate sheet steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many SM400B carbon steel plate sheet products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Semi-endless rolling technology has three advantages: the SM400B carbon steel plate sheet 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.

Our SM400B carbon steel plate sheet, hot rolled mild steel sheets offer excellent corrosion resistance property in the server’s environments. The mild steel sheets provide high resistance to nitric and chloride corrosion in sulfide solutions. These SA283 GrC carbon stel plates offer high strength, tensile, yield, mechanical strength, ductility, hardness, toughness, etc. Mild steel sheet is worked very easily in a high-temperature application and show excellent resistance to chloride crossing and cracking stress.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
