This group of Bulgarian (BDS) standards covers carbon, alloy and structural steels, free-cutting steels, plates for pressure vessels, hot-rolled plates, sheets and strips, high-temperature steel castings, welding filler rods, tool steels and electrical quality steels.
Review of BDS Standards for steel consists of 4 volumes.
It contains formally approved BDS standard classifications,
guides, practices, specifications, test methods, terminology
and related material such as proposals.
Covers:
The following data is given for each standard: standard number
and year, grade, chemical composition and mechanical properties
(yield point, tensile strength, notch toughness). When deemed
useful, steel type, manufacturing method, thickness of plate,
heat treatment and other data are described.
