Precision Engineered ASTM A182 F430 Blind Flange Manufacturer in India in Custom Sizes
Mortec Manufacturing Co forges Stainless Steel 430 flanges from traceable billets. Type 430 is a ferritic steel with high chromium. It carries zero nickel content. Stable pricing beats austenitic grades in volatile markets. This magnetic material expands less under heat. Buyers pick it for dry heat service. Machining follows ASME B16.5 and B16.47 standards. We supply RF FF and RTJ facing. Custom bore drilling matches your isometric drawing specs. All flange types move from Class 150 through 2500. Every dispatch carries PMI reports and mill certificates.

ASTM A182 430 SS Plate Flange
Cut From Plate • ASME B16.5- Profiled from certified ASTM A240 plate
- Cheapest route on low duty joints
ASTM A182 430 Threaded Flange
NPT and BSP • ≤4″ NB- Screwed joint avoids all hot work
- Works inside no welding permit zones
Stainless Steel 430 Orifice Flange
ASME B16.36- Tapped bosses carry the pressure taps
- Jack screws fitted when you ask
430 SS Spectacle Flange
MSS SP-44 • Figure-8- Swings between open and blanked positions
- Standard at shutdown isolation points
SS 430 Reducing Flange
ASME B16.5 • Two Bore Sizes- Steps the bore down without a reducer
- Saves both a weld and a fitting
AISI 430 Weld Neck Flange Chemical Composition
Composition limits per ASTM A182 Grade F430. Chromium alone builds the passive layer here.
There is no deliberate nickel and no molybdenum in this grade.

High Strength UNS S43000 Slip On Flange and Weld Neck Flange as per ASME B16.5 for Industrial Piping Systems
High Strength UNS S43000 Slip On Flange and Weld Neck Flange as per ASME B16.5 for Industrial Piping Systems
Type 430 carries useful strength at a nickel free price. Here is where it fits a piping spec.
What The Grade Delivers
Annealed F430 gives 450 MPa minimum tensile with 205 MPa yield. That covers most utility and dry service lines.
- Slip on for utility runs. The double fillet weld aligns quickly for tight access lines.
- Weld neck for pressure duty. The tapered hub takes a full butt weld through the joint.
- Nickel free pricing. Chromium alone builds the passive layer, keeping quotes off the nickel index.
- RTJ for tight seals. A Stainless Steel 430 Ring Joint Type Flange seats on a metal ring where a gasket will not hold.
- Know the limits. Chlorides, reducing acids and sub zero service need an austenitic grade.

Stainless Steel 430 Flange Dimension and Weight Basis
How every ASTM A182 F430 Blind Flange Size is fixed. Ring grooves on a Stainless Steel 430 Ring Joint Type Flange follow ASME B16.20.
Dimensions Follow ASME B16.5
Outside diameter bolt circle thickness and hub come from the standard. Nothing is invented in house.
Above 24 Inch Use B16.47
Larger diameters move to ASME B16.47 Series A or B. Confirm which series your project follows.
Weight Is Density Adjusted
Type 430 runs near 7.70 against 7.85 for carbon steel. Standard steel flange weights come down about two percent.

Stainless Steel 430 Flange FAQs
Five questions arrive with nearly every Type 430 enquiry. Answers stay plain below.
Are Stainless Steel 430 Flanges magnetic?
- Yes, Type 430 is a ferritic grade, so it pulls a magnet.
- It stays magnetic in every supply condition, spectacle flanges included.
- Pick 304 or 316 instead if you need non magnetic.
Which standard covers UNS S43000 Slip On Flange forgings?
- ASTM A182 Grade F430 covers the forging, matched by ASME SA182 F430.
- DIN 1.4016 answers to the same chemistry under EN naming.
- Plate cut work follows ASTM A240 Type 430 instead.
What sizes and classes are held in SS 430 Blind Flange?
- ASTM A182 F430 Blind Flange Size runs half inch to 24 inch NB in Class 150 through 1500.
- Above 24 inch we work to ASME B16.47 instead of B16.5.
- Weight sits near 7.7 g/cm3, so it ships lighter than 316.
Can AISI 430 Weld Neck Flange be used in seawater?
- No, there is no molybdenum, so chlorides pit the surface quickly.
- The same limit binds long weld neck and orifice flanges too.
- Use 316 or duplex for marine duty, keep 430 for dry service.
What documents ship with an ASTM A182 F430 Flange order?
- EN 10204 3.1 mill test certificate ships standard with every crate.
- Type 3.2 third party certification is available on request.
- Invoice, packing list, COO and PMI report ship with heat numbers stamped.
