In Aug. 2018, we produced High Cr Elbows, delivered to Germany.

1.There are two types of elbows:

ELBOW 80 MM 15°

ELBOW 80 MM 45°

Alloy Elbow
Alloy Elbow


2.We adopt sand casting process.The size tolerance is CT12,the surface finish is about Ra100.



3.The material grade is Cr2,which chemical composition is shown in the following Figure:

Composition (%)CSiMnCrCuPSHardness
Cr21.8-3.6≤1.00.5-1.51.5-3.5≤1.0≤0.06≤0.06About HB430


4.High chromium cast iron is the abbreviation of high chromium white anti-wear cast iron.It is much higher wear resistance than alloy steels, much higher toughness and strength than general white cast iron, at the same time, it also has good anti-high temperature and anti-corrosion performance, as well as convenient production, moderate cost, and has been praised as one of the best anti-wear materials of modern times.The material grade of high chromium white cast iron are BTMCr15, BTMCr20 and BTMCr26.The beauty label is ASTM A532;The Australian standard is AS 2027.
