This is a detailed, technical review of ASME BPVC Section II, Part A – 2019 Edition (Ferrous Material Specifications) . This review is intended for engineers, inspectors, procurement specialists, and students involved in pressure vessel manufacturing, repair, or quality assurance.
Comprehensive Review: ASME BPVC Section II, Part A – 2019 (Ferrous Materials) 1. Overview & Scope Full Title: ASME Boiler and Pressure Vessel Code, Section II: Materials – Part A: Ferrous Material Specifications Edition: 2019 (Published July 1, 2019) Organization: American Society of Mechanical Engineers (ASME) Purpose: This volume provides a complete, mandatory list of ferrous (iron-based) materials that are permissible for construction under ASME Sections I, III, IV, VIII, and XII. It adopts, modifies, or creates specifications based on ASTM standards. Key Statistics:
~1,200 pages (print edition) ~180+ individual material specifications Covers plates, pipes, tubes, forgings, castings, bars, bolts, fittings, and structural shapes.
2. Structure & Organization (2019 Update) The 2019 edition maintains the revised numbering format introduced in 2017. Specifications are grouped into four major series: | Series | Description | Examples | |--------|-------------|----------| | SA-20 to SA-39 | General requirements & plate specifications | SA-20 (General), SA-36, SA-285, SA-516 | | SA-40 to SA-169 | Bars, shapes, forgings, rivets | SA-105, SA-182, SA-350, SA-453 | | SA-178 to SA-269 | Pipe & tube (welded & seamless) | SA-106, SA-179, SA-192, SA-213 | | SA-270 to SA-1000 | Castings, fittings, bolts, specialty alloys | SA-216, SA-351, SA-352, SA-354, SA-962 | Mandatory Appendices: asme bpvc section ii part a 2019 pdf

3. Notable Changes in the 2019 Edition Compared to the 2017 edition, the 2019 version includes:
New Specifications:
SA-1066: Standard specification for normalized alloy steel plates for pressure vessels (high-strength, low-alloy). SA-1067: Seamless ferritic alloy steel pipe for high-temperature service (Grade 91 modified). Overview & Scope Full Title: ASME Boiler and
Revised Specifications:
SA-516/SA-516M (Pressure Vessel Plates, Carbon Steel): Clarified heat treatment requirements for Grades 65, 70. SA-182/SA-182M (Forged Austenitic Stainless Steel): Added Grade F62 (duplex stainless) with tighter chemistry limits for improved weldability. SA-106 (Seamless Carbon Steel Pipe): Updated permissible chemical composition for Grade B & C.
