M05

M05 is a special alloy material, which especially is  suitable for conditions with high impact load and good corrosion resistance. It is used in working condition when pH range is 5~12

≥58

5~7

ASTM A532 CL III-A

M07

Compared with M05, it has a slightly lower abrasiveness and good anti-impact performance, and it is more suitable for lowe abrasive conditions. It is used in working condition when pH range is 5~12

≥58

5~7

ASTM A532 CL III-A

M12

It has higher wear resistance than M05, but it is not resistant to corrosion. It is used in working conditions where the PH value is 6~14 and  M05 is not suitable.

60~67

2~5

M49

It has certain anti-impact and good corrosion resistance. It is used in the weak acid environment with pH range 4-6, especially suitable for flue gas desulfurization equipment in thermal power plants.

35~45

5~7

M33

It has certain anti-impact and corrosion resistance and is used for oxidizing slurry with pH =1,such as conveying phosphogypsum and medium such as nitric acid, sulfuric acid and phosphoric acid.

30-40

5~7

M61

M61 has better toughness than M12, and its matrix can be further harden by heat treatment, which can improove  the anti-abrasion performance.

60-67

5~6
