Full title and description

Welding consumables — Covered electrodes for manual metal arc welding of creep-resisting steels — Classification. ISO 3580:2017 specifies classification systems for covered (coated) electrodes used in manual metal arc welding of ferritic and martensitic creep‑resisting and low‑alloy elevated‑temperature steels, including rules for marking and identification of electrodes based on all‑weld‑metal chemistry and mechanical properties.

Abstract

ISO 3580:2017 defines a combined classification specification for covered electrodes using two complementary systems: (A) classification based on the chemical composition of the all‑weld metal together with requirements for yield strength and impact energy, and (B) classification based on tensile strength and chemical composition of the all‑weld metal. The document indicates which clauses and tables apply to either system A or B and provides provisions for electrodes that can be classified to both systems.

Scope

The standard applies to the classification of covered electrodes for manual metal arc welding where the welded material is ferritic or martensitic creep‑resisting or low‑alloy steels used at elevated temperatures. It covers classification criteria based on all‑weld‑metal chemical composition and mechanical test requirements (yield strength, tensile strength, impact energy) for the heat‑treated condition of weld metal, and provides rules for marking and identification of electrodes under the two classification systems described in the document.

Key topics and requirements

• Two complementary classification systems: system A (chemical composition with yield and impact requirements) and system B (tensile strength with composition requirements).
• Specification of test conditions and mechanical property requirements for all‑weld‑metal in the heat‑treated condition.
• Tables correlating electrode types across both systems where possible, and guidance on electrodes that meet both classifications.
• Marking, designation and identification rules for covered electrodes intended for creep‑resisting steels.
• Annexes/clauses identifying applicability of individual tables/requirements to system A or B (suffix A/B convention in the text and tables).

Typical use and users

Manufacturers of welding consumables, welding engineers, fabricators and quality‑assurance personnel in power generation, petrochemical, boiler and pressure‑vessel industries, and any organizations that manufacture or certify covered electrodes for welding creep‑resisting and elevated‑temperature steels. The standard is used for product specification, procurement, and conformity assessment of covered electrodes for service at elevated temperatures.

Related standards

ISO 3580:2017 supersedes earlier editions and related technical documents (for example ISO 3580:2004 and the original ISO 3580:1975 code of symbols). Regional/adopted versions exist (for example BS EN ISO 3580:2017 / national adoptions). Related welding and consumables standards include those covering qualification of welding procedures and testing of all‑weld‑metal properties referenced within the classification rules.

FAQ

Q: What is this standard?

A: ISO 3580:2017 is an international standard specifying classification and identification requirements for covered (coated) electrodes used in manual metal arc welding of ferritic and martensitic creep‑resisting and low‑alloy elevated‑temperature steels.

Q: What does it cover?

A: It covers two classification systems (composition plus yield/impact requirements, and tensile strength plus composition), the mechanical and chemical criteria for all‑weld‑metal in the heat‑treated condition, and the marking/identification rules for electrodes that meet these classifications.

Q: Who typically uses it?

A: Welding consumable manufacturers, welding engineers, fabricators in industries using high‑temperature steels (power plants, boilers, petrochemical, heavy industry), procurement and QA/QC personnel responsible for specifying or verifying electrode types.

Q: Is it current or superseded?

A: ISO 3580:2017 is the current published edition (edition 4, published April 2017) and replaced earlier editions such as the 2004 and 2010 versions; ISO standards are typically reviewed on a five‑year cycle and the ISO registry shows the 2017 edition as published/confirmed.

Q: Is it part of a series?

A: It is part of the family of ISO standards dealing with welding consumables and welding processes administered by ISO/TC 44 (Welding and allied processes) and is related to other standards that specify testing, qualification and product standards for welding electrodes and filler metals.

Q: What are the key keywords?

A: Covered electrodes, manual metal arc (MMA), creep‑resisting steels, all‑weld‑metal composition, tensile strength, yield strength, impact energy, electrode classification, electrode marking.
