Ganpat Industrial Corporation has forged and stocked alloy bar in Mumbai since 1997. Alloy Steel F11 Round Bar carries 1.00-1.50% chromium and 0.44-0.65% molybdenum, added so the bar keeps its strength past 425°C, the point where plain carbon steel starts to creep. We hold SA 182 F11 CL.1/2 Forged Bar across round, square, hex and flat sections, each normalized and tempered at our Mumbai facility. Every despatch carries an EN 10204 3.1 mill test certificate with full heat-number traceability. As an Alloy Steel F11 Round Bar Supplier in India, we regularly ship to Vadodara, Chennai and Kandla, and export to Dubai, Jebel Ali and Jubail.

F11 vs F12 vs F22 Alloy Steel Comparison
Buyers often weigh F11 against F12 and F22. We get asked this on almost every high-temperature enquiry.
Alloy Steel F12 Round Bar
- Lower chromium, 0.80-1.25% Cr
- Same 0.44-0.65% molybdenum range
- Slightly lower Class 1 yield (32 ksi min)
- Same DIN/EN 1.7335 family
Alloy Steel F11 Round Bar
- Higher chromium, 1.00-1.50% Cr
- Better oxidation resistance at temperature
- The most widely stocked CrMo forging grade
- Broadest global availability
Alloy Steel F22 Round Bar
- 2.00-2.50% Cr, 0.87-1.13% Mo
- Higher creep strength above 565°C
- Rated for continuous service to 621°C
- Higher alloy cost than F11
Alloy Steel F11 Round Bar
- Best value up to 565°C continuous service
- Easier to machine and weld than F22
- Lower cost for the same pressure class
- Preferred where F22 is over-specified
F11 Alloy Steel Forged Bars Manufacturing Process
From Billet To Certified Bar
A quick look at how F11 billet becomes a finished, traceable round bar.
Hot Rolling / Forging
Billet reduced to round, square or hex bar section
Normalizing
Heated 890-950°C then air cooled to refine grain
Tempering
Reheated 630-720°C to relieve stress and set hardness
Cold Drawing / Peeling
Bright and peeled bar sized to close tolerance
Inspection
Chemistry, hardness, straightness and PMI cleared
Dispatch
Tagged and shipped with EN 10204 3.1 certificate
