A washer is the cheapest part of a flange joint and the fastest way to spoil one. Ours are blanked from carbon steel carrying the 0.40% minimum carbon that A194 demands, then hardness-checked so the bearing face under your nut never flattens on first pull-up. Buyers reach an ASTM A194 Grade 2 Washers Supplier in India for one reason – they want the washer, the nut and the paperwork to arrive from a single heat instead of three unrelated vendors. Flat blanks for load spread, taper blanks for beam flanges, conical blanks where vibration loosens a joint: all pressed, tumbled and coated in-house, then packed size-wise with the heat number readable on the carton.

Heat Treatment & Tempering Of ASME SA 194 Gr 2 Washer
This is the only step that separates a Grade 2 blank from a Grade 2 blank.
Grade 2 Stress Relief
Minimum 1000°F [538°C] after forming or machining from bar
Hot-Forged Exemption
Blanks hot forged or cut from hot-rolled bar need no stress relief
Grade 2 Liquid Quench
Austenitised then quenched in liquid, never air cooled
Temper At 850°F Min
455°C minimum tempering pulls Grade 2 into its 248-327 HBW band
Re-Test Soak
Sample held 24 h at 1000°F [540°C], slow cooled, re-indented
ASTM A194 Grade 2 Washer Vs Grade 2H Washer – Which One To Order
Grade 2 Washer
- Stress relieved, not quenched
- Wide hardness band, 159-352 HBW
- Pairs with A307 and general bolting
- Lower cost per thousand pieces
Grade 2 Washer
- Liquid quenched and tempered
- Tight band, 248-327 HBW to M36
- Standard partner for A193 B7 studs
- Chosen for flanges, boilers and code work

Grade Marking On ASTM A194 Grade 2 Washer & Its Nut
Washers are traced by tag, not by face stamp – here is what the matching nut face must carry.
Hot Forged / Cold Punched
2 | 2
Plain grade symbol on one face
Machined From Bar
2B | 2B
Suffix B declares the bar route
Zinc Coated
2ZN
ZN added after the grade symbol
Cadmium Coated
2CD
CD added after the grade symbol
Stud & Nut Pairing Chart For A194 Gr 2 Washers
Match the washer to the joint, not to whatever is left in the bin.
A193 B7 Stud
Take Grade 2 nuts with Grade 2 washers – the standard refinery flange set
A193 B7M Sour Duty
Switch to Grade 2M at 159-235 HBW; plain 2 is too hard for H2S lines
A307 & General Bolting
Grade 2 washers are the economical fit for non-code, non-cyclic joints
F3125 Structural Bolts
Grade 2 is accepted in place of A563 DH on Type 1 structural assemblies
A320 L7 Cryogenic
Below -20°F move to A194 Grade 4 or 7 washers, not carbon steel Grade 2
Mixed Coating Sets
Keep stud, nut and washer on the same finish or torque scatter widens
ASME SA 194 Gr 2 Washer Temperature Limits & Coating Restrictions
The steel is rarely the limit – the plating usually is.
Zinc Coated Bolting
Below 390°F
210°C ceiling – guards against liquid metal embrittlement
Cadmium Coated Bolting
Below 300°F
160°C ceiling – cadmium melts near 600°F
Plain / Black Finish
Up To 800°F
427°C in common refinery flange practice
Low Temperature Duty
Not Below -20°F
Move to A320 sets with Grade 4 or 7 washers

Manufacturing Process Of Carbon Steel Gr 2 Washer
Coil & Bar Screening
Spectro reading confirms the 0.40% carbon floor before cutting
Blanking & Piercing
Press tools punch the OD and bore in one stroke for concentricity
Quench & Temper
Liquid quench then temper above 455°C for the Grade 2 band
Tumbling & Deburring
Bearing faces cleaned so the washer seats flat under the nut
Coating & Final Check
Plating, hardness indent and gauging before size-wise packing
Installation Guideline For A194 Gr 2 Washers
Put The Hardened Washer Under The Turned Part
Nut turning means washer under the nut; bolt turning means washer under the head
Step 1
One Washer Per Face, Never A Stack
Stacked washers hide grip length errors and let the joint relax
Step 2
Tighten In A Star Pattern, In Passes
Cross the flange at 30%, 60% then 100% of the target torque
Step 3
Use The Right Nut Factor For The Finish
Plain, zinc and PTFE washers all change the torque-to-tension result
Step 4
Re-Torque After The First Heat Cycle
Gasket creep shows up after start-up; check the joint once it has cooled
Step 5
Scrap Any Dished Or Galled Washer
A cupped bearing face has already given up part of its clamp load
Step 6
Surface Coating Options For A194 AS 2 Conical Washer
Self Colour / Black Oxide
Lowest cost, keeps the joint free of any temperature limit
Zinc Plated
Indoor and mild outdoor cover; keep service under 210°C
Hot Dip Galvanized
Thick zinc to ASTM A153 for coastal and buried structures
PTFE / Xylan
Low friction film that steadies torque scatter on repeat joints
Phosphate & Oil
Storage protection and a ready base under site paint

Frequently Asked Questions
Is A194 Grade 2 the same material as Grade 2?
Same chemistry, different furnace route. Grade 2 is quenched and tempered, which is why their hardness bands differ.
Does ASTM A194 actually cover washers?
A194 is a nut specification. Washers are supplied in A194 Grade 2 or 2 material with dimensions taken from ASME B18.22.1.
Why is A194 Grade 2 sold as alloy steel in catalogues?
It is a trade habit carried over from the A193 range. Grades 2 are carbon steel with 0.40% min carbon, not chromium-molybdenum steel.
Can Grade 2 washers go on structural bolts?
Yes. Grade 2 is accepted in place of A563 Grade DH on Type 1 assemblies, so one stock serves both piping and structural work.
What is the hardness limit for zinc plated washers?
Hardness stays the same, but keep zinc coated bolting below 210°C in service to avoid embrittlement risk from molten zinc.
What is your minimum order quantity?
100 pieces on stocked standard sizes. Pressed non-standard diameters are quoted against the drawing and usually ship in 7 to 10 days.
