What is the 09MnNiDR equivalent astm electric stove

Before welding, preheat should be carried out according to the 09MnNiDR equivalent astm welding process, and set up a good temperature measuring point.The number and thickness of weld layers, as well as the temperature between weld layers, should be controlled.And after each welding, the corresponding heat preservation treatment should be carried out.After 09MnNiDR equivalent astm welding the weld, and after 24 hours, then you can carry out ultrasonic nondestructive testing, but the ambient temperature should be up to the standard.

09MnNiDR equivalent astm, 15MnNiDR is a kind of steel plate for low temperature pressure vessel, which meets the specification of GB3531.Delivery status of 15MnNiDR: 15MnNiDR shall be delivered by normalizing or normalizing + tempering, with low temperature impact of - 45℃.Chemical composition analysis of 15MnNiDR: C: no more than 0.18, Si: 0.15-0.5, Mn: 1.2-1.6, P: no more than 0.02, S: no more than 0.008, Ni: 0.2-0.6, V: no more than 0.05.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 09MnNiDR equivalent astm heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported 09MnNiDR equivalent astm to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Integrity based:To customers, we should value our credit and keep our good image forever.To colleagues: respect each other, trust each other, make efforts togetherService first:Customer satisfaction is always the first pursuit.The company provides customers with not only advanced technology and high-quality 09MnNiDR equivalent astm products, but also the spirit of credit and service.Innovation:We are good at learning, drawing on the strengths of all, innovating and developing, introducing, researching and developing the latest technology, and making our products have a stronger vitality.
