GRADE R37

3 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.

Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Grade R37 · ISO 3304-1985

Original-source verification is incomplete; this is not a formal standard reference

Material category
Carbon steel
Subcategory
Carbon steel
Material form
Reference record
Verification status
Reference data; original source not verified

Carbon-equivalent reference

IIW / CEV: composition source not verified; standard-range carbon equivalent is not calculated
Pcm (Ito–Bessyo): composition source not verified; standard-range carbon equivalent is not calculated
CET: composition source not verified; standard-range carbon equivalent is not calculated

Composition

ElementComposition requirement
C≤ 0.17 (lower limit not stated)
Mn≤ 0.8 (lower limit not stated)
P≤ 0.05 (lower limit not stated)
S≤ 0.05 (lower limit not stated)
Si≤ 0.35 (lower limit not stated)

Applicability and limitations

A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
