ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon A514 Gr B quenched and tempered steel content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need is not so important.
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 A514 Gr B quenched and tempered steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
We do sand blasting and shop primer for various A514 Gr B quenched and tempered steel steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer A514 Gr B quenched and tempered steel thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A514 Gr B quenched and tempered steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A514 Gr B quenched and tempered steel steel, can be used as an alloying element of low alloy steel.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
