Gyscoal manufactures stainless steel angles are per IS:2062 Grade Fe 410W A/B/C. Our Angles are made after proper rolling and cutting and hence the tolerance of these angles is maintained as per IS:1852 specifications.
Chemical & Mechanical Properties of Steel Angles
Gyscoal Alloys Ltd. manufactures rail steel angles rolled from S.S. Billet or Ingot or flats or RCS as per ASTM specification A499-89*. This Steel is not supplied with specific mechanical (tensile and yield) properties, however the ASTM A-499 does provide the following guidelines:
Mechanical—Minimum requirements are set on tensile and yield strength.
Chemical—Chemical properties will be consistent with ASTM A1-92**.
