Description
There isn’t a standard material exactly named “1SS400GT2R” in major catalogs. It’s likely a vendor-specific code or a misread of a known grade.
If you mean SS400 (JIS G3101):
- Type: Low-carbon structural hot-rolled steel.
- Typical properties: Yield ≥ 245 MPa; tensile ~400–510 MPa; good weldability and formability.
- Composition (approx.): C 0.08–0.14%; Mn 0.30–0.65%; P ≤ 0.04%; S ≤ 0.05%.
- Uses: Structural members, frames, brackets, machinery frames.
- Treatments: Usually not heat-treated; may be annealed or normalized; surface finishes include painting or galvanizing.
If GT2R is a vendor-specific modification (heat treatment, coating, or grade variant), please share the supplier or the full spec sheet. I can interpret the exact meaning and recommended uses once I have that context.

Equivalent
I can’t determine exact equivalents without the datasheet for 1SS400GT2R. Please provide key specs (VR, IF, IFSM, VF) and packaging, or a link. Generally, cross-references for 1SS400-type diodes include other 1S-series parts (e.g., 1SS355/356/357) or, if specs match, common small-signal diodes like 1N4148/4149. For precise matches, use the manufacturer’s cross-reference tool or distributor data.
Pinout
- Pin count: 2 pins (anode and cathode)
- Function: Silicon switching diode (small-signal, fast-switching diode) used for general-purpose switching/rectification.

Application
1SS400GT2R is a JIS SS400-type structural carbon steel (low carbon, good weldability). Typical applications:
- General structural fabrication: welded frames, beams, columns, supports for buildings and bridges
- Machine components: frames, bases, brackets, gussets
- Light-duty automotive, agricultural, and trailer frames and parts
- Non-critical housings and enclosures in machinery and equipment
- Other welded fabrications requiring good formability and low cost (scaffolding, hardware, fixtures)
Note: used where strength requirements are modest and high weldability is needed.
