Cr30ni70 (executive standard GB / t1234-2012)

Chemical composition of cr30ni70:

Physical properties of cr30ni70:

Cr30Ni70

This alloy has the following properties:

70ni-30cr has high content of nickel and chromium and low content of iron. It has good oxidation resistance, thermal strength and low positive temperature coefficient below 1050 ℃. At room temperature, it has high plasticity, cold stamping and welding properties. The alloy is single-phase austenite after solution treatment, and its structure is stable in use.

Metallographic structure of cr30ni70:

Cr30ni70 alloy is single-phase austenite structure

The application fields of cr30ni70 include:

1. As a heating element, it is mainly used for periodic heat treatment furnace with temperature below 1050 ℃, such as carburizing furnace, bell jar furnace, etc., but it is rarely used

2. It can also be used as high-quality heat-resistant steel structure parts, such as shaft, burning frame, etc
