xar400 wear resistance material material welding
The characteristic of niobium in xar400 wear resistance material etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
In February, affected by the new crown epidemic, steel market demand was delayed and steel prices continued to fall. Since March, with the effective control of the new crown epidemic, the downstream industries have resumed production, the market situation has gradually improved, and xar400 wear resistance material and so on steel prices are expected to stop falling and stabilize.
Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business xar400 wear resistance material department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and xar400 wear resistance material after-sales service department constitute the service customer network.
The effect of elements in the wear plate on high temperature temper brittleness: chromium, manganese, nickel, silicon, etc. play a role in promoting, while molybdenum, tungsten, titanium, etc. play a retarding role, and carbon also plays a role in promoting. Generally, xar400 wear resistance material, carbon wear-resistant steel plates are not sensitive to high temperature tempering brittleness, while binary or multi-element alloy steels containing chromium, manganese, nickel, and silicon are very sensitive. The degree of sensitivity varies depending on the type and content of alloy elements.
