ASTM A145-34 PDF

Full title and description

St ASTM A145-34 — Standard Specification for Low‑Carbon Ferromolybdenum. This is an historic ASTM specification (designation A145, year suffix 1934) that provided purchase and quality requirements for low‑carbon ferromolybdenum (a ferroalloy used as a molybdenum source in steelmaking).

Abstract

ASTM A145-34 is a short, early ASTM specification issued in 1934 covering low‑carbon ferromolybdenum. The document is brief (historical record indicates only a few pages) and was later rendered inactive/withdrawn; contemporary ferromolybdenum requirements are covered by later international and national ferroalloy standards.

General information

• Status: Withdrawn / inactive (historically withdrawn around 1940; listed as inactive in standards databases).
• Publication date: 1934 (designation shown as A145-34; publication date listed as January 1, 1934 in standards records).
• Publisher: ASTM (original publisher: ASTM International / American Society for Testing and Materials).
• ICS / categories: Metallurgy — Ferroalloys / Iron & steel products (ICS family: 77 — Metallurgy; ferroalloys commonly classed under 77.100).
• Edition / version: A145-34 (1934 edition).
• Number of pages: Short document (recorded as 2 pages in standards catalog entries).

Scope

As issued, ASTM A145-34 specified requirements for low‑carbon ferromolybdenum — a ferroalloy product used mainly as a source of molybdenum for steelmaking and alloy production. Typical content of such a specification would include definition, chemical composition limits (emphasis on low carbon content), sampling and test requirements, and delivery/packing information; however, the original 1934 text is a brief historical specification and later international standards define more comprehensive requirements for ferromolybdenum.

Key topics and requirements

• Designation and scope for a low‑carbon ferromolybdenum product (historical specification — A145-34).
• Chemical composition focus (molybdenum content and low carbon requirement inferred from title and later ferroalloy practice).
• Sampling and testing clauses typical of ferroalloy specifications (sampling, chemical analysis methods, acceptance criteria — more fully developed in later ISO/ASTM ferroalloy standards).
• Delivery, packaging, and consignment/lot information as common in ferroalloy specifications.

Typical use and users

Users historically and today would include steelmakers, foundries, ferroalloy producers and suppliers, metallurgical engineers, quality / procurement teams specifying alloying materials, and standards librarians researching historical material specifications. For current procurement and technical requirements, users should consult up‑to‑date ferroalloy standards and supplier datasheets.

Related standards

Relevant modern and related standards include ISO 5452 (Ferromolybdenum — specification and conditions of delivery) and other ASTM/ISO documents covering ferroalloys, ferroalloy terminology, and testing methods. Users looking for current detailed requirements for ferromolybdenum should refer to these later standards rather than the 1934 A145 text.

FAQ

Q: What is this standard?

A: ASTM A145-34 is an historical ASTM specification titled "Standard Specification for Low‑Carbon Ferromolybdenum" (designation A145 with 1934 year suffix). It is a short, early specification for a ferroalloy product used in steelmaking.

Q: What does it cover?

A: The specification covered low‑carbon ferromolybdenum — addressing the product definition and basic requirements expected for that time (composition emphasis on molybdenum and low carbon, plus procurement/acceptance items). More comprehensive modern requirements are found in later ISO and ASTM ferroalloy standards.

Q: Who typically uses it?

A: Historically, metallurgists, steelmakers, foundries, ferroalloy suppliers, and procurement/specification engineers would reference A145-34. Today it is primarily of historical interest; current users should reference modern ferroalloy standards and supplier specifications.

Q: Is it current or superseded?

A: It is not current — catalog records list ASTM A145 (A145-34) as withdrawn/inactive (withdrawn around 1940 in historical records). Users should consult later standards (for example ISO 5452 and current ASTM ferroalloy-related documents) for up‑to‑date requirements.

Q: Is it part of a series?

A: A145 sits within ASTM's historical series of material and ferroalloy specifications. It is a single‑designation historical specification (A145-34). Related ASTM items address other ferroalloys and ferroalloy terminology; more recent consolidated references exist in ISO and in modern ASTM collections for ferroalloys.

Q: What are the key keywords?

A: Key keywords: ferromolybdenum, ferroalloy, molybdenum, low‑carbon, ASTM A145, A145-34, metallurgy, ferroalloy specification, withdrawn standard.
