Heat resistant castings are typically made out of stainless steels that have a high Chromium and Nickel count. Castings made out of heat resistant alloys are excellent for components exposed to dry gases at high temperatures for long periods of time. Industries that benefit from heat resistant castings include Energy, Engines, Furnaces/Ovens, and Petrochemical.
Heat resistant steel castings are also referred to as oxidation resistant steel castings, refractory steel castings, heat resistant stainless steel castings.
Heat resistant steel is a kind of alloy steel that has higher mechanical strength and better chemical stability at high temperatures.
Heat resistant steel castings have been used to make heat resistant components in industrial furnace, heat exchanger, thermal treatment furnace, grate cooler and other heat resistant industrial equipments.
The standard ASTM A297 covers iron-chromium and iron-chromium-nickel alloy castings for heat-resistant service, the grades covered by ASTM A297 are general purpose alloys and no attempt has been made to include heat-resisting alloys used for special production application.

Tube Shields
The service life of tube shields is has a great relationship with the selected material. Generally, high quality tube shields such as 310S have a longer service life. The normal service life of tube shield is an overhaul cycle (3-5 years). Generally, the boiler will replace or add some parts every time it is overhauled. The main parts to be replaced are those with serious wear, thinning and exceeding the standard. And also which fall off during the operation of the b...

Cast Alloy Guide Rollers, Guide ring/wheels
Guide roller is the main consumption tool of high-speed wire rod mill, which requires high wear resistance, steel sticking resistance and thermal fatigue resistance. Ordinary austenitic heat-resistant steel, martensite wear-resistant steel or wear-resistant cast iron guide roller can not meet the above requirements. Their service life are short, which reduces the operation rate of the mill. ...
