A204 GR.B steel mechanical properties

Yield Strength ReH: ≥275Mpa   
Tensile Strength Rm:485-620 Mpa
Fracture Elongation[%]：≥21  

ASTM A204 steel is for pressure vessel using, and it belongs to molybdenum-alloy steel plates. It is intended particularly for welded boilers and other pressure vessels. The maximum thickness of plates is limited only by the capacity of the composition, which is to meet the specified mechanical property requirements. In general, the thickness range of A204 Gr.B steel is 6-150mm.

As a Cr-Mo alloy steel with proper yield strength, A204 GR.B steel is mainly applied in manufacturing boilers and pressure vessels which are used for industrial usage. We have ever offered this material steel to our old customers for many times. Moreover, KUNFENG can offer various kindly deep processing work of A204 GR.C, rolling , cutting, shapping , chamfering, welding and finally installed the tanks. The A204 GR.B steel plate can be machined to A204 GR.B steel works/steel structures/steel machining parts according to your drawings. Shanghai KUNFENG has been working in the deep processing industry for many years. We have much experience in providing the A204 GR.B steel works/steel structures/steel machining parts.
