Zhangjiagang YaoYu Wear Resistant Materials Co.,Ltd supply high hardness wear resistant steel pipe with high quality, with nearly 10 years  experience in designing and

manufacturing different size hardfacing steel products for customers, and can offer the best wear solution according to the actual working conditions.
 
wear resistant composite steel pipe is a kind of new type high wear resistant composite material, it uses automatic CNC open arc hardfacing process and has a high

chromium wear resistant alloy layer welded inside the seamless steel pipe
 
The weld material is with following chemistry: Carbon 4.2~5.45% , Cr 25.3~30%, Si 0.7~1.5%, Mn 0.2~1%, Ni 0.1~0.4%, B 1~1.5%, Fe-balance
 
wear resistant steel pipe is also known as chromium carbide overlay pipe, which is suitable for mining equipment, cement equipment, metallurgical equipment, electrical

equipment manufacturing and fabrication industries with excellent wear resistance, excellent impact resistance, excellent deformation capability and welding ability.
1. OD: above 150mm
2. Specifications are : 6+4,6+5,6+6,8+4,8+5,8+6,10+4 etc. (base layer+ hardfacing layer)
3. Hardness: HRC 58-62
 
Generally, functionality of its wear resistance has the following statistics:
 
1.20- 25 times harder than low carbon steel pipe;
2.1.5-2.5 times harder than as-cast high chromium steel pipe;
3.5-10 times harder than tool steel pipe;
4.5-20 times harder than high manganese steel pipe
