Magnetic Grade SS 434 Bolts and Nuts Manufacturer in India With Ex-Stock Availability at Competitive Rates
Grade 434 sits exactly where a buyer needs it. Plain 430 keeps rusting at the thread root. SS 434 Bolts offer the same 16-18% chromium ferritic base. 434 Stainless Steel Fasteners add 0.75-1.25% molybdenum without a gram of nickel. This pushes pitting resistance up beyond plain 430. UNS S43400 Screws avoid blowing the budget the way 316 does. Procurement teams in Johannesburg, Dubai, Nairobi and Toronto order from our Mumbai plant. WNR 1.4113 Studs sit on the rack, not on a mill schedule.
The M3 to M64 range stays ready for AISI 434 Threaded Rod orders. Each consignment ships annealed, passivated and tagged to its heat number. SUS 434 Washers travel with mill test certificates in the same file. INOX 434 Nuts arrive alongside the invoice and packing list. ASTM A193 Type 434 Hex Bolts get headed, rolled and turned in-house. ASTM A193 Grade 434 Rivet orders never depend on a mill's schedule. ASTM A193 Gr 434 Dowel Pin drawings with non-standard lengths still get quoted. 434 Stainless Steel Hex Nut pricing comes from the shop floor, not a guess. SS 434 U Bolts with left-hand threads get a real lead time. X6CrMo17-1 Socket Head Cap Screw orders skip the trading desk entirely.

INOX 434 Nuts Annealing & Heat Resistance Limits
As a Stainless Steel 434 Fasteners supplier in India, process control ensures reliable material quality.
Cold Heading
Headed cold like 430 but with more force and allowance for springback.
Annealing
Soak at 760–830°C, then air cool to recover ductility after forming.
Service Ceiling
Scaling resistance holds to 815°C continuous and 870°C intermittent.
Embrittlement Watch
Avoid long holds near 475°C; the 400–550°C band costs toughness.
Welding Note
Grain coarsens in the heat-affected zone; 316L or 430 filler is usual.
Passivate & Gauge
ASTM A967 passivation, then hardness and go/no-go thread gauging.
AISI 434 Threaded Rod Applications
Where the molybdenum addition earns its keep against salt, humidity and flue heat.
UNS S43400 Screws Governing Manufacturing Standards
Every Stainless Steel 434 Fasteners Manufacturer in India verifies chemistry, dimensions, and documentation before shipping.
SS 434 Bolts Chemical Composition
AISI 434 is grade 430 with molybdenum added, and because nickel is not a specified element, the price remains stable.
WNR 1.4113 Studs Mechanical Properties
ASTM A240 specifies minimums for annealed grade 434, while ferritic 434 cannot be strengthened by quench hardening.

SS 434 vs SS 430 vs SS 316 Fasteners
The three-way call most specifiers make before signing off exterior or washdown bolting.
SS 430 (S43000)
- Family: Ferritic, chromium only
- Molybdenum: Not specified
- PREN: About 16 to 18
- Magnetic: Yes, strongly
- Best For: Dry indoor trim and appliance work
- Relative Cost: Lowest of the three
SS 434 (S43400)
- Family: Ferritic, chromium-molybdenum
- Molybdenum: 0.75 to 1.25%
- PREN: 18.5 to 22.1
- Magnetic: Yes, strongly
- Best For: Coastal air, road salt, humid outdoor duty
- Relative Cost: Modest step up from 430
SS 316 (S31600)

- Molybdenum: 2.00 to 3.00%
- PREN: Around 24 and above
- Magnetic: No, in the annealed state
- Best For: Immersed and chemical service
- Relative Cost: Highest, tracks nickel pricing

Straight answers from the plant that heads, rolls and passivates the goods.
Are Stainless Steel 434 fasteners magnetic?
Yes, SS 434 bolts are strongly magnetic due to their ferritic structure, unlike austenitic bolting.
What is the difference between 430 and 434 stainless steel fasteners?
434 stainless steel fasteners add molybdenum, raising PREN for better resistance in coastal, salt washdown duty.
What is the equivalent grade of UNS S43400 screws?
WNR 1.4113 studs, SUS 434 washers (JIS), 434S19 (BS 970), X6CrMo17-1 per EN designation.
Can AISI 434 threaded rod be hardened by heat treatment?
No, ferritic INOX 434 nuts and rod won't harden by quenching; strength comes from cold working.
What standards and temperature limits apply to ASTM A193 Type 434 hex bolts?
Rated to 815°C continuous; avoid holding 400-550°C. Covered by ASTM A193 Grade 434 and ISO 3506.
