ASTM A1020 PDF

This specification covered minimum wall thickness welded tubes made from carbon and carbon manganese steels, with various grades intended for use in boiler, superheater, heat exchanger, or condenser applications. This standard is being withdrawn without replacement due to its limited use by industry. Grade D Carbon Manganese Steel. Tubing having other dimensions may be furnished provided such tubes comply with all other requirements of this specification.

Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Flat Rolled Products by 42 distributors but is also available to a lesser extent in Bar Products, Tubular Products, Structurals, Fasteners, Forging Products, Piping Components, and Wire Products.

Principal Design Features is one of the very commonly used plain carbon steels. It has a nominal carbon content of 0. It is a good combination of strength and ductility and may be hardened or carburized. Applications steel is used for simple structural application such as cold headed bolts. It is often used in the case hardened condition. Forming Formability is good by all conventional methods as the ductility of is good.

Welding Readily weldable by all of the standard methods. Heat Treatment may be hardened by heating to - F and then water quenching. It should then be tempered. More often it is used as case hardened by carburizing. The cost of doing any heat treatment to such a low carbon steel often precludes doing so for the modest return in mechanical properties obtained.

Forging Forge at down to F. Hot Working Hot work in the range of to F. Cold Working steel is readily cold worked by all conventional methods. A stress relief anneal may be needed after extensive cold work. Annealing A full anneal is done at to F followed by slow furnace cooling.

This will give a tensile strength of about 65 ksi. A stress relief anneal may be done at F. Aging Not applicable. Tempering Temper, following heat treatment and quenching, at to F depending upon strength level desired. A F temper gives a tensile strength of 90 ksi. Hardening steel hardens by cold working an by heat treatment, quenching and tempering.

Formability is good by all conventional methods as the ductility of is good. Readily weldable by all of the standard methods. Forge at down to F. Hot work in the range of to F.

A full anneal is done at to F followed by slow furnace cooling. Not applicable. Temper, following heat treatment and quenching, at to F depending upon strength level desired. Mean Coeff Thermal Expansion. Modulus of Elasticity Tension. Modulus of Elasticity Torsion.
