Working with A1011 SS-36-T2

Is A1011 easy to machine?

Cuts easily but is gummy — sharp tools, positive rake and good chip evacuation; deburr and expect mill scale to be abrasive on the first pass.

Can A1011 be welded?

Excellent with GMAW/GTAW/RSW/laser; CS and DS need no preheat, HSLAS and UHSS grades require low-hydrogen consumables and controlled heat input to avoid HAZ softening.

Can A1011 be formed, bent or molded?

CS/DS shear, punch, roll-form and stamp readily; allow larger bend radii and higher springback compensation as you move up SS/HSLAS/UHSS strength levels.

What surface finishes work on A1011?

Descale (pickle/blast) then phosphate + paint, powder coat, e-coat or hot-dip galvanize; bare A1011 rusts within days in humid storage.

A1011 SS-36-T2 — frequently asked

What is A1011 SS-36-T2 used for?

A1011 SS-36-T2 is typically used for stamped parts, structural brackets, tube skelp and general fabrication. In short: widest strength range hot-rolled; cheapest stamping-grade steel; excellent weldability, score 95.

What is the yield strength of A1011 SS-36-T2?

A1011 SS-36-T2 has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 435 MPa (63.1 ksi) — weaker than 86% of steel grades. Strength varies by condition: see the 37 listed tempers.

Is A1011 SS-36-T2 easy to machine?

Reasonably — machinability is rated good (58/100, better than 75% of steel grades). Cuts easily but is gummy — sharp tools, positive rake and good chip evacuation; deburr and expect mill scale to be abrasive on the first pass.

Can A1011 SS-36-T2 be welded?

Yes — weldability is rated excellent (92/100). Excellent with GMAW/GTAW/RSW/laser; CS and DS need no preheat, HSLAS and UHSS grades require low-hydrogen consumables and controlled heat input to avoid HAZ softening.

What surface finishes work on A1011 SS-36-T2?

Descale (pickle/blast) then phosphate + paint, powder coat, e-coat or hot-dip galvanize; bare A1011 rusts within days in humid storage.

Can A1011 SS-36-T2 be formed, bent or molded?

CS/DS shear, punch, roll-form and stamp readily; allow larger bend radii and higher springback compensation as you move up SS/HSLAS/UHSS strength levels.

What is the maximum service temperature of A1011 SS-36-T2?

A1011 SS-36-T2 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between A1011 CS-B and A1011 UHSS-90?

CS-B is the default condition — the default stocked hot-rolled commercial sheet: lowest-carbon CS type, best weldability and bending of the CS family. UHSS-90: entry ultra-high-strength hot-rolled sheet for light-weighting where forming is simple. Yield strength is 250 MPa in CS-B versus 660 MPa in UHSS-90.
