Sus301 Temper Stainless Steel Coils Strip Vickers 430 Jis 1250mm

SUS301 Temper 3/4H Vickers 370-430 JIS G4313-2012 SUS301 3/4H STAINLESS STEEL STRIP
Specification of our products:

Stainless steel grade 301 is usually supplied in the form of strips and wires, with a tensile strength of up to 1800 Mpa, to produce tempers ranging from 1/16 Hard to Full Hard. By subjecting grade 301 to controlled analysis it is capable of retaining sufficient ductility even in ½ hard conditions. This form of grade 301 may be used in aircraft, rail car components and architectural structures. Tempers of this grade, ranging from ¾ to full hard, may be used in applications requiring high wear resistance and spring features with simple form designs.
Grade 301L, which is the low carbon form of grade 301, is the ideal choice for applications that require good ductility. Grade 301LN is another variant. This contains a higher percentage of nitrogen and exhibits a higher work harden rate compared to standard 301. Only grade 301 is specified in ASTM A666. 301L and 301LN are represented by other conventions. Grade 301L is represented by JIS G4305 and 301LN by EN10088-2 as grade 1.4318.

Key Properties

The key properties listed in the below sections are for flat rolled products such as plate, sheet and coil - specified as Grade ASTM A666. For other grades, EN10088.2 and JISG4305, it is not necessary that the values and properties are identical.

Composition

Composition ranges of stainless steel grade 301 are tabulated below.

Corrosion Resistance

The resistance to corrosion offered by stainless steel grade 301 is similar to that offered by 304. This grade exhibits good resistance to corrosion in mildly corrosive environments at ambient temperatures.

Heat Resistance

Grade 301 exhibits good oxidation resistance for intermittent services up to 840°C and for continuous service up to 900°C.

Heat Treatment

Stainless steel grade 301 is subjected to solution treatment annealing in temperatures ranging from 1010oC to 1120°C followed by rapid cooling. For intermediate annealing a low temperature range is chosen. Thermal hardening does not suit this grade of stainless steel.

Cold Working

Stainless steel grade 301 and low carbon variants of this grade are predominantly used as high strength stainless steel. The work hardening rates of these grades are very high, in the range of a 14MPa increase per 1% reduction in area of cold work. As a result of this characteristic high strength can be achieved from cold rolling and roll forming operations.
Through such forming methods strain hardened austenite may be partially transformed to martensite. In spite of achieving such high strengths, the residual ductility in the alloy is capable of causing severe cold deformation. The alloy is non-magnetic in the annealed condition, but shows strong magnetism when cold worked.

Welding

Stainless steel grade 301 is suitable for all forms of standard welding methods. The use of grade 308L as filler metal is recommended. Welded parts in grade 301 must be subjected to annealing in order to attain maximum corrosion resistance. For grades 301L and 301LN annealing is not necessary after welding. The purpose of welding followed by annealing is to remove the high strength brought about by cold rolling.
The process of spot welding is used to assemble the cold rolled 301 components; this rapid welding technique does not hamper the overall strength of the component.

Applications

Some of the typical applications of grade 301 stainless steels are listed below:

• Making rail car structural components
• Air frame sections
• Highway trailer components
• Automotive wheel covers
• Wiper blade clips and holders
• Stove element clips
• Screen frames
• Toaster springs
• Curtain walls
