ASTM A513 1015 Tubes – Grade 1015 Carbon Steel ERW & DOM Mechanical Tubing

ASC LLP, Mumbai, supplies ASTM A513 1015 tubes. This is Grade 1015 low-carbon, electric-resistance-welded (ERW) mechanical tubing, available as-welded or drawn over mandrel (DOM), in round and shaped sections, cut to length, with mill test certificates. See our carbon steel tubes and DOM tubes.

What are ASTM A513 1015 Tubes?

ASTM A513 is the specification for electric-resistance-welded carbon and alloy steel mechanical tubing – tube for machine parts, automotive components and fabricated structures rather than pressure piping. Grade 1015 is a low-carbon steel with 0.13 – 0.18% carbon and 0.30 – 0.60% manganese. It is softer and more ductile than 1020 or 1026, so it is chosen where tubes must be bent, flared, swaged or welded easily.

A513 tube is always welded – it is not seamless. For seamless mechanical tubing see ASTM A519.

A513 1015 – Quick Facts

Specification: ASTM A513, Grade 1015 (SAE / AISI 1015)
Types: Type 1 / 2 as-welded, Type 5 DOM
Conditions: as-welded, normalised, as-drawn, drawn and stress-relieved
Shapes: round; square and rectangular on request
Certificate: mill test certificate (EN 10204 3.1)

Features of A513 Grade 1015 Tubing

Easy to form: low carbon gives good ductility for bending, flaring, expanding and swaging.
Very good weldability: no preheat needed for normal wall thicknesses.
Machinable: suitable for turned and threaded parts, especially in DOM form.
Choice of condition: DOM for close tolerances and higher strength; normalised for maximum ductility.
Corrosion: plain carbon steel – supplied oiled; paint, plate or coat for outdoor service.

1015 vs 1020 vs 1026 – Which Grade?

1015 – lowest strength of the three, best for forming and bending.
1020 – the general-purpose grade; see A513 1020 tubes and 1020 DOM tubes.
1026 – highest strength, used for hydraulic cylinders and shafts; see A513 1026 tubes.

Frequently Asked Questions – ASTM A513 1015 Tubes

What is ASTM A513 1015 tubing?

ASTM A513 1015 is electric-resistance-welded mechanical tubing made from SAE 1015 low-carbon steel (0.13–0.18% C, 0.30–0.60% Mn). It is supplied as-welded or drawn over mandrel (DOM) and is chosen for easy bending, flaring and welding.

Is A513 1015 tubing seamless?

No. ASTM A513 covers only electric-resistance-welded tubing. Seamless mechanical tubing is made to ASTM A519.

What is the yield strength of A513 1015?

Per the A513 property tables, minimum yield is 35 ksi (241 MPa) as-welded, 55 ksi (379 MPa) for DOM as-drawn and 50 ksi (345 MPa) for DOM stress-relieved. Normalised tube has a minimum yield of 30 ksi (207 MPa).

What is the chemical composition of A513 1015?

A513 Grade 1015 contains carbon 0.13–0.18%, manganese 0.30–0.60%, phosphorus 0.035% max. and sulphur 0.035% max.

What is the difference between 1015 and 1020 tubing?

1020 has slightly more carbon (0.18–0.23% vs 0.13–0.18%), giving a few ksi higher strength in the same condition. 1015 is a little easier to bend, flare and weld.

How is A513 1015 tubing sized?

A513 mechanical tubing is ordered by actual outside diameter and wall thickness (or OD and ID), for example 1.000″ × 0.065″, not by nominal pipe size or schedule.
