Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the jis g4051 s45c s50c mild steel, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.
jis g4051 s45c s50c mild steel, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.
Try to use jis g4051 s45c s50c mild steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the jis g4051 s45c s50c mild steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
Our quality and service commitment: jis g4051 s45c s50c mild steel product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment.
