Production Description

Hastelloy C - 4 (UNS NO6455)

Features and application field overview:

The alloy is an austenitic low carbon nickel-molybdenum-chromium alloy. The main difference between Nicrofer 6616 hMo and other alloys of similar chemical composition developed earlier is the low carbon, silicon, iron and tungsten content. Such chemical composition makes it exhibit excellent stability at 650-1040ºC, and improves its resistance to intergranular corrosion. Under appropriate manufacturing conditions, it can avoid the edge line corrosion sensitivity and weld heat affected zone corrosion. Alloys are used in flue gas desulfurization systems, pickling and acid regeneration plants, production of acetic acid and agricultural chemicals, production of titanium dioxide (chlorine), electroplating, etc.

Metallographic structure:

The alloy is surface centered cubic lattice structure, and its chemical composition guarantees the metallographic stability and resistance to sensitization.

 

Performance and requirements:

1. Do not contact sulfur, phosphorus, lead and other low-melting metals in the process of heat treatment, otherwise the alloy will become brittle. Please pay attention to remove dirt such as marker paint, temperature indicator paint, colored crayons, lubricating oil, fuel and so on. The lower the sulfur content in the fuel, the better. The sulfur content in natural gas should be less than 0.1%, and the sulfur content in heavy oil should be less than 0.5%. Electric furnace heating is a better choice, because the furnace can accurately control the temperature, clean furnace gas. If the gas furnace gas is pure enough, you can choose.

2. The hot processing temperature of the alloy ranges from 1080ºC to 900ºC, and the cooling method is water cooling or other rapid cooling method. In order to ensure the best anticorrosion performance, solid solution heat treatment should be carried out after hot working.
