nm550 steel wear resistance 2000 tons exported to Malaysia

At present, NM550 steel wear resistance abrasion resistant steel plate thickness is between 8-100mm, the hardness of up to 500HBW. Thin steel sheet and ultra-wide steel plate has been developed for special use.

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn NM550 steel wear resistance seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black NM550 steel wear resistance line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This NM550 steel wear resistance rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
