ASTM A213/A213M-25 PDF

Full title and description

ASTM A213/A213M-25 — Standard Specification for Seamless Ferritic and Austenitic Alloy‑Steel Boiler, Superheater, and Heat‑Exchanger Tubes. This specification covers the manufacture, heat treatment, mechanical testing, and acceptance requirements for seamless ferritic and austenitic alloy‑steel and stainless‑steel tubes intended for boilers, superheaters, and heat exchangers.

Abstract

The standard specifies grades, chemical and mechanical requirements, permitted sizes, heat‑treatment and finishing practices, and mandatory tests (tension, hardness, flattening, flaring, plus nondestructive electric or hydrostatic testing). Grades designated with an “H” include elevated creep‑rupture requirements; certain grades (for example TP347HFG) have specific finishing or heat‑treatment instructions.

General information

• Publication date: January 9, 2025 (designation A213/A213M‑25).
• Publisher: ASTM International.
• ICS / categories: 23.040.10 — iron and steel pipes / heat‑exchanger and boiler tubing.

• Number of pages: 16 pages.

Scope

Applies to seamless ferritic and austenitic alloy‑steel and stainless‑steel tubes used for boilers, superheaters, and heat exchangers. Typical sizes range from about 1/8 in. (3.2 mm) ID up to 5 in. (127 mm) OD with minimum wall thicknesses commonly from 0.015 to 0.500 in. The specification includes both inch‑pound and SI (M) units; the inch‑pound system applies unless the “M” designation is specified in the order. Grades with the “H” suffix have alternate requirements to provide higher creep‑rupture strength.

Key topics and requirements

• Material types and grade designations (ferritic alloy steels and austenitic stainless steels; e.g., T‑grades and TP‑grades).
• Chemical composition limits and grade tables for listed alloys.
• Permitted tube sizes, tolerances, and wall‑thickness provisions (both minimum and average where specified).
• Manufacturing methods: seamless, hot‑finished or cold‑finished processing; specific finish requirements for certain grades (e.g., TP347HFG).
• Heat treatment requirements and options (including reheat, solution treatment, and quenching where applicable).
• Mandatory mechanical and acceptance tests: tension, hardness, flattening, flaring, plus nondestructive electric testing or hydrostatic testing for each tube lot.
• Special provisions for H‑grades to address creep‑rupture strength at elevated temperatures.

Typical use and users

Used by manufacturers, material specifiers, boiler and heat‑exchanger fabricators, mechanical engineers, procurement specialists, and inspection agencies. Typical applications include boiler and steam generator tubes, superheater and reheater tubing, and high‑temperature heat‑exchanger service in power generation, petrochemical, and process industries.

Related standards

ASME SA‑213 is the ASME designation commonly paired with ASTM A213 for pressure‑vessel/boiler code usage (SA‑213 is the code specification counterpart). Other related ASTM standards include A179 (seamless cold‑drawn heat‑exchanger and condenser tubes), A249/A249M (welded austenitic boiler and heat‑exchanger tubes), A269/A269M and A312/A312M (stainless tubing/piping standards), A335 (seamless ferritic alloy‑steel pipe for high‑temperature service), and general tube requirements such as A1016/A1016M. These documents are frequently cross‑referenced when selecting tubing for specific service conditions.

FAQ

Q: What is this standard?

A: ASTM A213/A213M‑25 is the ASTM International standard specification for seamless ferritic and austenitic alloy‑steel and stainless‑steel boiler, superheater, and heat‑exchanger tubes; the “M” indicates the SI‑unit (metric) variant where specified.

Q: What does it cover?

A: It defines grades, chemical and mechanical requirements, permitted sizes and tolerances, heat‑treatment and finishing instructions, and mandatory tests (tension, hardness, flattening, flaring, plus nondestructive electric or hydrostatic testing). Grades with an “H” include requirements for higher creep‑rupture performance.

Q: Who typically uses it?

A: Tube manufacturers, material engineers and specifiers, boiler and heat‑exchanger fabricators, procurement and quality inspectors, and organizations following ASME boiler and pressure vessel code requirements. Suppliers and purchasers reference it for material acceptance and testing.

Q: Is it current or superseded?

A: The A213/A213M‑25 edition is the current active ASTM designation (published January 9, 2025). Users should confirm the active status before purchase or specification, as standards are periodically revised.

Q: Is it part of a series?

A: Yes — A213 belongs to a family of tube and pipe specifications used for heat‑exchanger, boiler, and pressure‑service applications and is commonly cross‑referenced with ASME SA‑213 and related ASTM tubing/pipe standards (for example A179, A249, A269, A335, and A1016).

Q: What are the key keywords?

A: Boiler tubes, superheater tubes, heat‑exchanger tubes, seamless, ferritic, austenitic, creep‑rupture (H‑grades), nondestructive testing, hydrostatic testing, TP‑grades (stainless), T‑grades (alloy ferritic).
