Ador grade for any IS classification

An Indian tender, a drawing or a works procedure will often name the electrode by its IS designation, not by an AWS class and not by a brand. This table takes that designation and gives you the Ador grade, with the AWS class beside it so you can check the two agree. Every code below is the one Ador print in the classification block of their own datasheet for that grade — nothing here is derived or inferred.

Seven Indian Standards cover the range we stock. If your drawing cites a standard that is not here, send it to us — it is usually a base-material standard rather than a consumable one.

IS 814 — 17 grades

Covered electrodes — mild steel and low-alloy

IS 1395 — 12 grades

Covered electrodes — low and medium alloy steel

IS 5206 — 35 grades

Covered electrodes — corrosion and heat resisting steel

IS 5856 — 15 grades

Solid wires and rods — stainless and heat resisting steel

IS 6419 — 12 grades

Solid wires and rods — low alloy steel

IS 8736 — 9 grades

Covered electrodes — nickel and nickel alloy

IS 5511 — 4 grades

Covered electrodes — cast iron

Reading an IS designation

The IS 814 code is built from the covering type, the strength and toughness class, and the running characteristics — so EB5426H3X is a basic-covered electrode of that strength and impact class, with a controlled-hydrogen and recovery suffix. You do not have to decode it: the table above is the lookup. What matters in practice is that the IS code and the AWS class on the same row describe the same electrode, which is why both are printed here.

Where a designation lists more than one grade, the grades differ in covering, welding position, recovery or packing rather than in class. Open the grade page for composition and mechanical properties, and tell us the diameter and pack size you need.

Designations are read from Ador’s published datasheets, from the classification block on each sheet. A classification match is a starting point, not a substitute for the procedure — confirm the current datasheet before you weld. Where a procedure calls for a class approval by name, see our class-approved consumables page.
