AISI 416 / DIN 1.4005 Stainless steel plates

AISI 416 / DIN 1.4005 Stainless steel plates

416 Stainless Steel is a martensitic free machining grade of stainless that can be hardened by

heat treatment to achieve elevated strength and hardness.

Due to its low cost and ready machinability, 416 stainless steel is readily used in its highly tempered state.

It exhibits better machining characteristics than austenitic grades, however, sacrifices corrosion resistance.

Since stainless steel 416 is free of high sulfer content, it is not suitable for marine or any chloride exposure situations.

Best Stainless provides 416 stainless steel under the highest quality UNS S41600 and ASTM A582 standards.

416 SS can be utilized in a number of capacities and applications including, pump shafts, valve components, and

automatic screw machine parts. Stainless steel 416 is composed of carbon, chromium, manganese, phosphorous,

silicon, and sulfur.

Chemical composition ( % ) 

Carbon             0.150 max

Chromium       12.0- 14.0 

Manganese     1.250 max

Phosphorous  0.060 max

Silicon              1.00 max

Sulfur                0.150 max

Molybdenum   0.60 max

Applications 

A wide variety of screw machine parts including nuts, bolts, screws, gears and pinions, valve trim, shafts and axles. 

Machinability 

Speeds and feed comparable with those of some of the free machining carbon steels.

Good chip breakage. Material heat treated at 200°F and cold drawn will give best results.  

Welding 

Welding of any type is not recommended, as the high sulfur content creates porosity.  

Hot working 

All hot work procedures should commence following uniform heating to 2100-2250°F (1149-1232°c).

Hot work below 1700°F (927°c) may result in cracking.  

Cold working 

This alloy will accept only minor cold working. Severe deformation will result in cracking.  

Annealing 

1200-1400°F (650-760°c), air cool. For maximum softness, 1500-1650°F (816-900°c), furnace cool.  

Tempering  

Temper to achieve properties desired. Avoid tempering in the range of 750-1050°F (399-566°c) to avoid a decrease in

impact strength and corrosion resistance.  

Hardening  

Soak at 1700-1850°F (927-1010°c) oil quench.
