Free Machining 416 Stainless Steel

From one stainless steel to another.

Free machining 416 stainless steel.

Alloy 416 is a martensitic free machining chromium steel alloy that is generally considered to be the first free machining stainless steel. General characteristics of stainless steel 416. It identifies the stainless steel types that were developed to improve machining production and it demonstrates through illustrative examples that stainless steels are readily machinable. Magnetic in all conditions.

It has the highest machinability of any stainless steel at about 85 of that of a free machining carbon steel. Alloy 416 is a martensitic free machining chromium steel alloy that is generally considered to be the first free machining stainless steel. Martensitic stainless steels were designed to be hardenable by. This alloy is a free machining version of type 410 stainless steel.

The traditional free machining stainless steel grades have been based on sulphur s additions in the uk or alternatively selenium se additions which have been favoured in the united states. The addition of phosphorus and sulphur is responsible for improved machinability but results in some disadvantages such as lower impact values and poor weldability. Table 1 compares common grades of free machining stainless steel grades. Applications of stainless steel 416.

Its main function is to allow fast machining with a good surface finish and minimum tool wear. Martensitic stainless steels were designed to be hardenable by heat treatment and also. T 416 is quite simply described as a free machining modification of t 410. Free machining stainless steels grades introduction.

Grade 416 steel is a free machining stainless steel with a machinability of 85 highest of all stainless steels. The free machining variation of type 410 is type 416 and for type 420 the specifier should consider type 420f. Dec 2013 try for free. However the steel is designed for free machining and it is the best of all the stainless steels.

Common free machining stainless grade steels. Has same basic properties as type 410 good corrosion and oxidation resistance plus high strength in the hardened and tempered condition. Even on high volume high speed automatic screw machines. With most of the free machining stainless steels the machinability can be improved by adding sulphur which leads to the formation of manganese sulphide inclusions.
