P275NH normalizing can weld refined grain steel. Fine grain steel A573 Gr 70 plateis understood to be steel with ferrite grain size of 6 or finer after testing according to EURONORM103 standard. Executive standard: EN10028-3, number: 1.0487. P275NH is non-alloy quality steel for pressure equipment. P275NH steel plate has good plasticity, toughness, cold bending performance and welding performance.
The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A573 Gr 70 plate production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
TMCP process is an indispensable technology for our production of low alloy high strength wide and A573 Gr 70 plate thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy A573 Gr 70 plate and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.
Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. A573 Gr 70 plate, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.
Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
