What is p275nh1 material fatigue limit

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced P275Nh-steel-plate-material-for-vessel-steel-plate.html target=_blank class=infotextkey>P275NH1 material production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, P275Nh-steel-plate-material-for-vessel-steel-plate.html target=_blank class=infotextkey>P275NH1 material steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

For the hot pressing of the head, the initial temperature is 930-950℃, and the final pressing temperature (that is, the temperature at the time of demolding) should not be lower than 850℃. If P275Nh-steel-plate-material-for-vessel-steel-plate.html target=_blank class=infotextkey>P275NH1 material the temperature drops to close to 850℃, it cannot be pressed. It should be quickly returned to the furnace and heated before pressing.

The production process of P275Nh-steel-plate-material-for-vessel-steel-plate.html target=_blank class=infotextkey>P275NH1 material, 14Cr1MoR hydrogen-resistant Cr-Mo steel: electric furnace steelmaking - LF furnace refining - VD furnace vacuum degassing - rolling plate - flaw detection - normalizing - tempering - steel plate finishing - performance inspection. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high - temperature corrosion resistance of 14Cr1MoR steel.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
