The customer gave a high praise on our quick service as follows:

We sincerely hope to use our professional technology of wear-resistant, heat-resistant and corrosion-resistant to provide customers with high quality and cost-effective casting and forging services.

ASTM A297 HK is a well-known ferro chrome nickel alloy. The increase of chromium content at high temperature increases the resistance to oxidation, while the higher nickel and carbon content guarantees the austenite structure.Therefore, the grade is applicable to applications requiring high strength and corrosion resistance, ranging from 1200 to 1600 F (649 to 871 ℃), and is widely used in refineries and heat treatment furnaces.
