316 Stainless Steel Forging

316L (low carbon version) of 316 - UNS S31600/S31603

Anderson Shumaker produces 316 stainless steel open die forgings to meet exacting specifications. 316 stainless steel is the second most common stainless steel grade (after 304 stainless steel) and is commonly used in food and surgical stainless steel applications. The addition of molybdenum prevents specific forms of corrosion. By keeping the carbon below 0.03% max in this austenitic alloy has shown to minimize carbide precipitation during welding. Decreasing the sulfur in this grade will enhance its ability for electro-polishing. 316 SS is also known as marine grade stainless steel due to its increased resistance to chloride corrosion in comparison to 304 SS. 

316L stainless steel is an extra low carbon grade of 316 stainless steel; generally used in stainless steel watches and marine applications.

Applications: 316 Stainless is widely used in manufacture of manways, pharmaceutical equipment, valve bodies, bleaching and dyeing equipment for the textile industry and the food industry. 316 Stainless is resistant to atmospheric corrosion, food products, sterilization solutions and many organic chemicals as well as a variety of inorganic chemicals.

Chemistry Analysis
Carbon max 0.03% Manganese max 2.00%
Phosphorus max 0.045% Sulfur max 0.030%

Molybdenum 2.00 - 3.00 %    

 

Corrosion Resistance

The following table is for reference only, many factors can affect the corrosive resistance, a corrosion test for each application should be applied.

Phosphoric Acid Moderate Acetic Acid Good
Sodium Hydroxide Moderate Sea Water Moderate
Salt Spray Good Nitric Acid Good
Sulfuric Acid Moderate Humidity Excellent
Sour Oil/Gas Moderate  

 

Heat Treatment

Annealing:
Heat to 1850/2050 F (1010/1121c) and quench in water. Brinell hardness approximately 150.
Hardening:
Cannot be hardened by heat treatment. Cold working this alloy increases its strength and hardness, although best corrosion resistance is in the annealed condition.
Machinability:
When machining 316 stainless steel its chip characteristics will be tough and stringy, when machining the use of chip curlers and breakers should be considered.  Since Austenetic grades work harden rapidly, heavy positive feeds should be considered.  If machining a heavy amount of material, another anneal may prove beneficial.  Check out our machining option for you project. 
Specifications:
