Description
SINOXX 4435 is often substituted for 316 stainless due to its superior weldability with no appreciable difference in price or properties. It combines good availability in all forms and size ranges with great strength and corrosion resistance.
Applications
Components used in marine environments and chemical equipment. Suitable for any application where 316 stainless is used and stronger welds are desirable.

Forging
Hot forming temperature: 1200-900oC, slow cooling in air.
Machinability
Low speeds and constant feeds will minimize this alloy's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.
Welding
All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 316L filler metal for best results.
Corrosion Resistance
Resistant to a wide variety of marine environments, salts, dilute nitric, acetic and sulfuric acids.
Cold working
Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.
