Ganpat Industrial Corporation has forged and stocked alloy steel fittings in Mumbai since 1997. AISI 4130 Buttweld Fittings carry 0.8-1.1% chromium and 0.15-0.25% molybdenum. This provides a strong balance of strength and weldability. Drilling and aerospace buyers ask for this low carbon chromoly chemistry by name. We manufacture elbow, tee, reducer, cap, cross, stub end, collar, and coupling fittings. These follow an ASTM A234 manufacturing basis. They are dimensioned to ASME/ANSI B16.9 and ASME B16.28. Every heat carries UNS G41300 traceability from billet to finished fitting. Each despatch includes an EN 10204 3.1 mill test certificate. An EN 10204 3.2 certificate is also available on request. We regularly ship this range to Vadodara, Chennai, and Kandla. We also export to Dubai, Jebel Ali, Dammam, and Houston.

AISI 4130 vs ASTM A234 WPB Carbon Steel Fittings
Trust an AISI 4130 Buttweld Fittings Manufacturer in India for critical oilfield piping solutions.
ASTM A234 WPB Carbon Steel
- Lower cost, widely available
- No chromium or molybdenum addition
- Service typically capped near 425°C
- Fine for general utility piping
AISI 4130 Buttweld Fittings
- 0.8-1.1% Cr plus 0.15-0.25% Mo for hardenability
- Higher strength-to-weight after heat treatment
- Preferred for aerospace and high-pressure oilfield lines
- Good fatigue resistance under cyclic load
AISI 4140 Buttweld Fittings
- Higher carbon (~0.38-0.43%) than 4130
- Greater through-hardening strength
- Lower weldability without preheat
- Used where 4130 strength is insufficient
AISI 4130 Buttweld Fittings
- Lower carbon for easier field welding
- Preferred when repair welding is expected
- Good combination of strength and toughness
- Standard first choice for chromoly piping
