NACE MR0175 Certified ASME SA 193 Grade B7M Screw and Studs Manufacturer in India For Sour Service
When your line runs sour, a hardness certificate isn't optional, it's the difference between a joint that lasts and one that cracks under stress corrosion. That's why refinery and gas-plant buyers across the Middle East, Africa and the Americas come to us for ASTM A193 B7M bolts. Every ASTM A193 B7M stud, hex bolt and threaded rod we ship is tempered to the lower B7M strength band and hardness-checked before it leaves our Mumbai stockyard.
Grade B7M carries the same chromium-molybdenum chemistry as standard B7, but with the tempering and hardness control that NACE MR0175 / ISO 15156 sour-service specifications demand, and that holds whether it's a heavy hex bolt or an anchor bolt off the same bar. As a direct manufacturer we forge, machine, heat-treat and test in-house, so there's no trader layer between your RFQ and the mill. Whether you need emergency replacement stock for a shutdown or a container-load for a new build, our grade desk confirms diameter, length and thread before you commit.

ASTM A193 Grade B7M Equivalent
This ASTM A193 B7M Equivalent remains a US specific NACE grade without an exact match elsewhere. Verify hardness and tempering before substituting.
ASTM / ASME (USA)
- ASTM A193 / A193M Gr B7M
- ASME SA193 Gr B7M
- Mating nut: ASTM A194 Gr 2HM
DIN / EN (Germany) – Close Match
- 1.7225 (42CrMo4)
- 1.7220 (34CrMo4)
- Not a certified B7M substitute
JIS (Japan) – Close Match
- SCM435 type Cr-Mo steel
- Heat treatment differs from B7M
Sour Service Reference (UK/International)
- NACE MR0175 / ISO 15156
- Same qualifying standard as B7M
Difference Between B7 And B7M Bolts
The real ASTM A193 B7M Vs B7 difference is tempering, not chemistry. Only the hardness cap qualifies B7M for sour service, and we stock both grades directly.
ASTM A193 Grade B7 Bolts
- Tensile Strength: 125 ksi (≤2-1/2″ dia)
- Yield Strength: 105 ksi (≤2-1/2″ dia)
- Hardness Cap: None specified
- Sour Service: Not NACE qualified
- Best For: General high-temperature bolting
ASTM A193 Grade B7M Bolts
- Tensile Strength: 100 ksi (all covered dia)
- Yield Strength: 80 ksi (all covered dia)
- Hardness Cap: 235 HBW / 99 HRB max
- Sour Service: NACE MR0175 / ISO 15156 qualified
- Best For: Wet H2S, sour gas, subsea wellheads

ASTM A193 B7M Bolts FAQs
Here are quick answers to what buyers ask us most before they place an order.
What is the standard price basis for Grade B7M Threaded Rod?
Price is quoted per kg against the day’s alloy steel bar rate, plus diameter, length, thread type and testing level - share your spec for a firm number.
What is the difference between ASTM A193 Grade B7 and B7M bolts?
Both share the same Cr-Mo chemistry. B7M is tempered lower (100 ksi tensile, 235 HBW cap) for NACE sour service, while B7 is stronger with no hardness cap.
What is the ASTM A193 Gr B7m Material equivalent?
ASME SA193 B7M mirrors ASTM A193 B7M directly. For other systems, EN 1.7225 or JIS SCM435 offer close chemistry matches, but confirm tempering and hardness against your spec.
Do you supply ASTM A193 Grade B7m Hex Bolts to UAE and Saudi Arabia?
Yes - we ship as manufacturer and stockist to ports across the UAE, Saudi Arabia and wider GCC with full export documentation and MTC.
What torque should be applied to ASTM A193 B7M Stud?
Torque depends on diameter, lubrication and target bolt stress, so we don't publish one figure. Share your specs and we'll return a joint-specific value with your quote.
