SUS 430LX
2 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.

Applicability and limitations
The original table specifies Ti or Nb 0.10–1.00%; select the stabilization element actually used; It is not mandatory for both to be satisfied simultaneously. ; Table 5 Note a: Ni≤0.60%. ; Heat-analysis mass fractions wt%; Clause 5.2: Product analysis deviations shall follow JIS G0321 Table 5; items not specified require agreement, and the default heat analysis range shall not be expanded. ; This standard covers cold-rolled stainless steel plate, sheet and strip.; This does not establish applicability to the supply of cold-heading wire.. ; Elements not specified in the table shall not be filled as zero; The conventional low-alloy steel formula for carbon equivalent is not applicable to this type of stainless steel.

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.
