Stainless Steel 416
Description
416 Stainless Steel is a martensitic, free-machining stainless steel. By adding sulfur, its machinability is significantly improved, making it the easiest stainless steel to machine among all grades. It offers good strength and hardness after heat treatment but reduced corrosion resistance compared to 304 or 316. It is magnetic in all conditions and is widely used for precision parts requiring high machinability and moderate corrosion protection.

Introduction to Stainless Steel 416

What
Stainless Steel 416 (UNS S41600) is a martensitic stainless steel developed to maximize machinability. The sulfur addition breaks up chips during machining, improving tool life and productivity on CNC lathes and mills. It can be hardened through heat treatment, reaching high strength and wear resistance. However, its corrosion resistance is lower than other stainless steels, limiting its use to less aggressive environments such as dry atmospheres, mild chemicals, or fresh water.
Advantages
Best machinability among all stainless steels
Can be hardened by heat treatment for high strength
Good dimensional stability during machining
Cost-effective for high-volume CNC production
 
 
 
 
 
 
Applications
