Steel Materials
Characteristics: Low cost, good workability, exhibits diverse property changes through heat treatment, and is easy to recycle.
Note: The characteristic values below are standard values, not guaranteed values.
- Stainless Steel
- SUS304: General-purpose stainless steel, used for food equipment and general scientific equipment. It has good corrosion resistance and is non-magnetic.
- SUS316: An improved version of SUS304 with added molybdenum. Its corrosion resistance, acid resistance, and seawater resistance are superior to SUS304. It is also non-magnetic.
- SUS440C: Martensitic stainless steel. Its corrosion resistance is inferior to austenitic series (like SUS304), but it can be hardened by heat treatment (quenching) and is magnetic.
- Steel Types
- Structural Steel (e.g., SS400): Used for general mechanical parts. Features good workability and weldability.
- Carbon Steel (e.g., S45C, S50C): Used for general mechanical parts. After quenching and tempering, S45C achieves a tensile strength of 690 N/mm² or more and a hardness of HB 201~269. S50C offers higher performance.
- Chromium Molybdenum Steel (e.g., SCM435): Used for high-strength parts like bolts. After quenching and tempering, its tensile strength can reach 930 N/mm² or more.
- High Carbon Chromium Steel (e.g., SUJ2): Used for wear-resistant parts such as shafts and bearings. After high-frequency quenching, its hardness can reach 58 HRC or more.
- Hot-rolled Steel Plate (e.g., SPHC): Used for general mechanical structural parts. It is sheet metal with an oxide scale surface, commonly used for thicknesses under 6mm.
- Cold-rolled Steel Plate (e.g., SPCC): Used for making covers, casings, etc. It is sheet metal with a clean surface and high dimensional accuracy, featuring good workability and weldability.
- Stainless Steel, Austenitic Series (e.g., SUS303): Used for rust-proof mechanical parts like bolts and nuts. It has good machinability but average corrosion resistance and is non-magnetic.
