Product Description

WHY CHOOSE US

In addition to providing the widest range of materials to many different sectors, we are the only company who can melt and forge according to customer requests and produce in the form closest to the final product. We provide services that will increase the added value in products by adding our mechanical processing and heat treatment capabilities to our forging products, which are produced in requested forms from automotive to energy, from maritime to mold industry.

Stainless Steel 422 (AMS 5655)

Alloy 422 is a hardenable stainless steel designed for use at temperatures of up to 1200ºF (649ºC). Alloy 422 has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. Alloy 422 is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting etc.

Machineability

• Comparable to 18-8 but easier to machine
• Help avoid galling with sharply ground tools
• Maintain consistent speed and feed
• Turning tools: 8-14° side rake
• Drilling: 140° point
• Threading: grind tools with 10-15° back rake
• Cobalt high-speed tools: turn at 90-120 sfpm, drill at 40-75 sfpm, mill at 70-120 sfpm, ream at 20-60 sfpm, roughing and finishing at 200-400 sfpm

 

Workability

• Initial forging and rolling at 2100° to 2150°F (1149° to 1177°C)
• 1700°F (927°C) minimum to hot work
