Equivalents are approximate. See the grade equivalents guide.
SAE 4130 billets and blooms
4130 billets and blooms suit parts that are forged then welded, such as fittings and flanges.
Kesari Alloys supplies SAE 4130 as continuous cast billets and blooms from 100 × 100 to 250 × 250 mm and 200 mm round, in lengths up to 12 metres. See the billet size chart for weight per metre.
Heat treatment: Normalised, or hardened and tempered. Its lower carbon makes welding easier than 4140.
Typical uses of SAE 4130
- Pressure vessel and pipe fittings
- Oil field equipment
- Structural forgings
- Flanges
Industries: the valve industry, oil field equipment, power plant components, flange forging.
