NM400 Steel Plate is a type of wear-resistant steel plate that is commonly used in various industrial applications.
NM400 steel plates are demanded widely by many commercial industries as they offer great wear resistance, high strength and thus significantly improving wear resistance of heavy mechanical parts.
They are also known as wear–resistant plates. As compared to ordinary or low alloy steel mechanical properties of NM400 steel plate is 3 to 5 times more. Thus, the service life of this grade alloy helps to reduce the cost of production. The processing and manufacturing of the product of structural steel plate is done according to the suitability and necessity of the customers. Mostly this grade is brought into application in various manufacturing enterprises.

Wear resistant steel plate refers to the special plate products used under large area wear condition. At present, the commonly used wear-resistant steel plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates.
The series of NM wear-resistant steel combined the properties including high strength, high hardness, high wear resistant, weldable, bendable and mainly applied in:
304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.
Type 316 is more resistant to atmospheric and other mild environments than Type 304.
310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.
317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance.
Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.

06Cr19Ni10 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
