Product Overview

Description

SUS305  for used auto parts japan , thickness 0.01-1.5mm,width 3.0-300mm,        

1.Features(Overview)

SUS305 is generally referred to as non-magnetic stainless steel.
The common austenitic stainless steel SUS304 (18Cr8Ni) undergoes a martensitic transformation that endows it with magnetic properties (i.e. it attaches to magnets easily) when cold worked. Since SUS305 (which is also an austenitic stainless steel) has a high nickel (Ni) content that produces a stable austenite phase, it can maintain a state in which hardly any martensite is induced after cold rolling.
Their increased nickel content allows SUS305 materials to maintain non-magnetic properties after processing. The SUS305M grade that we produce has a nickel content that is toward the higher side of the JIS standard, and therefore provides higher non-magnetic properties.
Its high nickel content also gives SUS305M excellent workability and corrosion resistance.

 

 

2.Main uses 

Communication equipment parts, medical instruments, and motor parts (coin type)

*Due to its non-magnetic properties, SUS305M is used in electronic device component applications where magnetism is undesirable.

5.Why our customers love doing business with us

a) Special specs, Custom-made metals & foils

 At Tokkin, based on our diverse and proven track record of over 50,000 products, we use proprietary technologies and facilities developed in house to meet the needs of our customers.

We create custom-made products that reflect your requirements in terms of thickness, hardness, crystal granularity, and other characteristics.

 

b) Global supply-chain

Our global supply chain can provide you with raw materials and introduce you to our manufacturing centers and sales locations to suit your needs.

Base Metals

We can procure raw materials both locally and internationally for any type of steel or non-ferrous metal.

Balancing quality, cost, and delivery time frame, we will help you select the ideal raw material for your needs.

 

Works & Sales Offices

To respond to the constantly evolving market, we established manufacturing centers in Taiwan in 1988, in Shanghai, China, in 1998, and a second site in China in 2007. Under the slogan, "All Tokkin Standard," we manufacture products of the same quality at all our sites.

We opened a sales office in Hong Kong in 2012, and through our sites in Japan, Taiwan, China, and Hong Kong, and our distributors, help customers from around the world to procure materials of Japanese quality.

 

c) Small quantities, Quick delivery

If we have the product you need in stock, we can ship it in a few days in lots as small as 1 kg.

We can manufacture custom-made products in lots of 300 kg or larger (lots of 50 kg or larger also possible depending on the material) in four weeks.

We provide you with special spec materials to suit your needs in small lots with short delivery times.

 

d) High-precision thickness

We guarantee severe thickness tolerances to help you improve quality and reduce processes. 

Thickness tolerance example:

  - Thickness of less than 0.30 mm: Tolerance ±1 to 3 μm possible

  - Thickness of 0.30 mm and over: Tolerance ±1% possible

e) Multiple features

We not only manufacture single metal materials, but also manufacture single metals with additional functions like those below.

No other manufacturers are capable of making products that combine multiple functions from a diverse range of options.

 

f) Metal structure control

We can control metal structure using the cold rolling and heat treatment technologies that we have developed over the years to suit your application and requirements.

These technologies provide a range of advantages including improved hardenability, wear resistance, workability, and strength; reduced surface roughness due to bending and drawing; and prevention of sheared surface chipping.

 

g) Lower total cost

We offer products that help you reduce total cost by considering downstream processes.

 

6. Manufacture process

 

  

Manufacturing Processes	Outline
Base metal	We carefully balance quality, delivery time and price, procure various base matals from all over the world. We manufacture appropriate products to your needs.
Cold rolling	We have rolling machines like 18-high mills (Z-High type), 24-high mills (Sendzimir type), and 4-high mills, etc. We choose suitable rolling machine for each specification of metals. An AGC program in rolling machines controls pressure and position, enables an accuracy of ±1~3μm at thicknesses 0.20 mm or less, and ±1% at thickness greater than 0.30 mm in cold rolling process.
Annealing	We possess BA (Bright Annealing; Continuous-Type ), BELL(Bell-Type), and TA (Tension Annealing; Continuous-Type ) furnaces. Annealing for internal stress removal is also possible as well as soft annealing. Moreover, according to our accumulated experience and know-how, we can control the size of metallographic structure (carbide grain size).
Surface inspection (CCD)	All-digital processing by CCD camera detect surface defects. This high precise inspection machine detects even the minute scratches on a flat surface.
Slitting	Saitama plant has 7 different type of slitting machines, so we use the appropriate machinery for your metals and specifications. We can guarantee high quality slitting, like width tolerance and burr by setting optimum conditions for each metal's specification.
Sample inspection	We have furnished all the measuring equipments for mesuring metal properties and specifications, such as hardness and tension, etc. We also possess SEM (Scanning Electron Microscopes ) with EDX function. Furthermore, we have FE-SEM (+EBSD+EDS) which is more precise than SEM, so we can analyze micro crystal structure, too.
Packing	In order to prevent damage, rust, or other flaws arising in our products under transit, we alter our package one by one. We also accept specific packaging requests from you.
