Book Alloy K500 Rod and Hex Bar Supplier In India For Oil And Gas Downhole Tool Applications

Precipitation hardening lifts Monel K500 Round Bar's yield strength past 585 MPa while leaving the alloy's seawater and hydrofluoric-acid resistance fully intact - exactly why oilfield and marine engineers specify it over standard Monel 400 wherever extra strength or spring memory is needed. Kanakratna Steelage solution-anneals, age-hardens and cold-draws this UNS N05500 grade at our own Mumbai works, with hardness and ageing-cycle data recorded against every heat on the EN 10204 3.1 mill certificate that ships with your order.

Our Mumbai units run closed-die and GFM forging alongside precision bar rolling and centreless grinding, so round, hex, square and flat K500 forms all leave the same certified floor - never routed through a trading intermediary. ISO 9001:2015 and AQSR-PED 2014/68/EU registrations back every batch, and an active IEC keeps cross-border shipment moving without delay. Pune, Bengaluru, Rajkot and Ahmedabad fabricators reorder from us for that same heat-to-heat consistency, while our export desk moves Alloy K500 Rod to 20+ countries across the Gulf, Asia and Africa on a standing sailing schedule. Overseas buyers increasingly choose us as their preferred Monel K500 Round Bar Supplier in India.

Frequently Asked

Is Monel K500 Magnetic?

Curie Point: −134°C (−210°F)Relative permeability ≤1.005 - genuinely non-magnetic at every service and room temperature
Monel 400's Curie point sits near room temperature; K500's sits at −134°C, genuinely non-magnetic throughout.
Performance Data

Age-Hardening Heat Treatment For AMS 4676 Bright Bar

Solution Anneal (Soften)
850–1000°C (1560–1830°F), air or water quench
Age Harden
580–610°C (1075–1130°F), 4–16 hours by section, furnace cool to ~480°C
Ageing, not cold work, precipitates Ni3(Al,Ti) and takes K500 to its full hardened strength.

Choosing The Right Grade

Monel 400 vs Monel K500 Bar- Choosing The Right Alloy

Same base nickel-copper chemistry, very different jobs - here's the practical difference buyers ask us about most.

Monel 400 (UNS N04400)
Solid-solution, not age-hardenable276–414 MPa yield typical
Weakly magnetic near room tempCurie point +21 to +49°C
Easier to machine and weldNo post-weld strength loss to manage
Monel K500 (UNS N05500)
Precipitation-hardenable with Al+Ti586–827 MPa yield age-hardened
Genuinely non-magneticCurie point −134°C
Best for shafts, springs & downhole toolsWork-hardens fast, machine before ageing
Pick 400 for straightforward hardware; pick K500 for extra strength or a non-magnetic component.

Age-Hardened (AH, standard supply)
24–35 HRC - order this for shafts, springs and fasteners ready to use
Cold-worked-then-aged stock reads near the top of that range - tell us your target HRC.

Buyer Questions

Monel K500 Round Bar FAQs

What is Monel K500 Round Bar made of?

63% minimum nickel with 27-33% copper, plus 2.30-3.15% aluminium and 0.35-0.85% titanium for age-hardening.

Is Monel K500 the same as Monel 400?

No - K500 adds aluminium and titanium for precipitation hardening, nearly doubling Monel 400's tensile strength.

Is Monel K500 magnetic?

No - its Curie point of -134°C keeps K500 genuinely non-magnetic at every service and room temperature.

Does Monel K500 meet NACE MR0175 for sour service?

Yes, when supplied to QQ-N-286 Form 2 with hardness controlled to ISO 15156-3 sour-service limits.

What determines the Monel K500 round bar price?

Order quantity, diameter, ageing condition, testing level and current LME nickel-copper rates set the price.

What is the Monel K500 round bar price in India right now?

It moves daily with nickel and copper rates - share your size and quantity for an ex-Mumbai quote.

Can Monel K500 be welded?

Welding removes age-hardened strength in the joint area, so most fabricators weld annealed stock then re-age it.

Which industries buy Monel K500 Round Bar most often?

Oil and gas downhole tools, marine propeller shafts, valve trim, springs and fastener manufacturing worldwide.
