The A588 Grade B railway steel cold brittleness from BBN

Chrome-Moly low alloy steel A588 Grade B railway steel series contains 0.5% - 9% Cr and 0.5% - 1% Mo and lower than 0.20% carbon. 40CrNiMoA, 4340 and SNCM439 are the low alloy chromoly steel materials from the different standards. 40CrNiMoA steel A588 Grade B railway steel is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials A588 Grade B railway steel. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the A588 Grade B railway steel special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.

The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel A588 Grade B railway steel products have received high recognition from customers from the world. The company adheres to the operating principles of equality and mutual benefit and abides by the contract. We sincerely welcome you to visit us, negotiate business cooperation, enhance friendship, develop and expand trade.
