What are the differences between black and painted nm550 steel wear resistance

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the NM550 steel wear resistance industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the NM550 steel wear resistance industry with scientific management, high quality, first-class service and harmonious development

Hardness is the characteristic of providing excellent wear-resistant protection during the whole service life of wear resistant steel plate. High hardness minimizes wear because the sharp edges of the abrasive are difficult to cut into a hard surface. Wear resistant steel plate can be used for bucket, loader, dump truck, powder concentrator, chute and various wear-resistant lining plates. NM550 steel wear resistance, Wear resistant steel plate can withstand any form of wear from a variety of rocks, sand and gravel.

After quenching and tempering, 40Cr alloy steel plate and NM550 steel wear resistance sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel NM550 steel wear resistance is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard NM550 steel wear resistance pipe, X42 steel plate/pipes as large diameter pipes. X42 steel plate/pipes is one mainly of Steel for large diameter pipes, API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.
