Qiming Casting Products

Material Capacity

As a professional wear-resistant parts foundry, Qiming Casting can produce wear parts of different materials according to customer needs.

Manganese Steel

Manganese steel, or Hadfield steel or mangalloy, is a steel alloy containing 12-14% manganese. Renowned for its high impact strength and resistance to abrasion in its hardened state, the steel is often described as the ultimate work-hardening steel.

Material Grades:

ASTM A128
AS2074 H1A/-H1B
BS 3100
GX 130 MnCr
SCMnH11
GB/T 5680-2010

Manganese Steel Castings

Chrome Steel

Chrome steel, also called chrome white iron, has numerous applications in any application involving severe abrasive wear, including liners for chutes, apron feeders, crusher chambers, etc.

Alloy Steel

Alloy steel casting is the steel casting process in which numerous elements are alloyed with each other in total amounts between 1.0% and 50% by weight to improve their mechanical properties. Alloy steels are divided into two groups: low-alloy steels and high-alloy steels. Low-alloy steels are most commonly used in wear-resistant parts.

Material Grades:

AS2074 L2B (Cr-Mo alloy steel)
AS2074 L2C (Cr-Mo alloy steel)
42CrMo
35CrMo
40CrNiMo
Ni-Hard

Ceramic Matrix Composite

Metal Matrix Composites (MMC) are composite materials that combine metal matrix and ceramic reinforcement materials to achieve better physical properties. They can meet various customer needs, such as maintaining the original shape and weight and improving rigidity, keeping the original rigidity and reducing weight, or achieving better heat dissipation performance.

Metal Matrix Composites (MMCs) have significantly transformed the benchmarks for wear-resistant materials within high-abrasion sectors such as mining, cement, and recycling. In the face of escalating competition and heightened operational requirements, enterprises leverage sophisticated MMC solutions to enhance the performance and durability of their equipment.

Carbide Inlay

Carbide inlay refers to the process of casting TIC carbide rods in a high-manganese steel matrix to extend the product’s service life.

Our engineers inlay the titanium carbide rods on the working surface of the liner. When the stone enters the crushing chamber, it first comes into contact with the raised titanium carbide rods, which wear very slowly due to their ultra-hardness and wear resistance. At the same time, due to the protective effect of the titanium carbide rods, the matrix of the high manganese steel also slowly comes into contact with the stone, and the matrix hardens.

Material Grades:

Mn18Cr2+TIC
Mn22Cr2+TIC
Alloy Steel +TIC

Bimetallic Composites

Bimetallic composites are exceptional laminated products resistant to impact and abrasion while retaining ductile characteristics by bonding high-chromium cast iron onto mild steel backing plates. The bonding shear strength is over 210 Mpa and will not separate.

High-chromium cast iron, with a hardness of at least 63 HRC, provides very high wear-resistant qualities, while the steel backing plate absorbs high impacts and allows easy use and installation with no pre-heating when welding.

Material Grades:

High chromium + Mild steel
High chromium + Tungsten + Mild steel
