Stainless Steel 904L Angle builds strong structural frames surviving harsh fluids. High nickel chromium molybdenum and copper content protects against severe chemical corrosion. Added copper performs exceptionally well in dilute sulphuric and hot phosphoric acids. Standard 316L material fails quickly in these aggressive industrial acid environments. We supply hot rolled and precision laser fused angles for demanding applications. All bars are properly annealed and pickled then cut to your list. Every single bar ships with EN mill certificates and full PMI proof. Ganpat Industrial Corporation delivers custom lengths across global markets with fast shipping.

Never at the fillet, where metal is naturally thicker.

Confirm Squareness

Out-of-square legs cost you time at weld fit-up.

Check Straightness

Bow and twist over the full 6 m bar, before cutting.

SS 904L Angle – Frequently Asked Questions

How is Stainless Steel 904L Angle priced per kg?

LME nickel and molybdenum set the base. We rate per kg on your size, thickness and tonnage – rate back in 24 hours.

Which sizes can I order in SS 904L Angle?

Equal Leg Angle 25x25x3 to 200x200x15 mm. Unequal Leg Angle 45x25x4 to 200x150x15 mm. Bars 6000 mm, sawn to your list.

What is the per metre weight of UNS N08904 Angle?

Section area in cm² times 0.795, at 7.95 g/cm³. So 50x50x5 mm is 3.82 kg/m and 100x100x10 mm is 15.22 kg/m.

Under which specification is WNR 1.4539 Angle bar supplied?

Material to ASTM B649 and ASME SB-649. Tolerance to EN 10056-2 or ASTM A484. Laser fused to ASTM A1069.

Can 904L SS Channel, I Beam and Chain ship along with the angle?

Yes. U Channel, C Channel, I Beam, H Beam and Chain come off the same N08904 heat, one certificate, one dispatch.
