14Cr1MoR is a special steel plate for pressure vessels, which belongs to Cr-Mo hydrogen-resistant steel.
14Cr1MoR hydrogen-resistant steel specification: 14Cr1MoR performance code GB/T713-2014.
14Cr1MoR steel plate chemical composition:C ≤0.17; Si 0.50~0.80; Mn:0.40~0.65, P:≤0.02, S: ≤0.010, Ni:≤0.3; Cr:1.15~1.50, Mo:0.45~0.65, Cu:≤0.30
Production process of 14Cr1MoR hydrogen-resistant steel plate:Production process of hydrogen-resistant Cr-Mo steel: electric furnace steelmaking-LF furnace essence-VD furnace vacuum degassing-rolling plate-flaw detection-normalizing-tempering-steel plate finishing-functional inspection. The company formulates suitable internal control components and strictly controls the chemical composition to shake the scale to ensure the stability of the steel plate function. Strengthen ingredient control and exercise operation, effectively control the content of harmful elements such as Sn, Sb, As, Cu, etc. In addition to low P and S content, improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. Select control heating to ensure the heating time and temperature, select control rolling and other methods to ensure the quality of the steel plate. Strictly control the rolling and heat treatment processes, so that the steel plate can obtain a reasonable arrangement structure and grain size to ensure that the steel plate has an excellent induction function.
