Steel - Conversion of elongation values - Part 1 : carbon and low alloy steels
This document specifies a method of converting room temperature percentage elongations after fracture obtained on various proportional and non-proportional gauge lengths to other gauge lengths. Formula (1), on which conversions are based, is considered to be reliable when applied to carbon, carbon manganese, molybdenum and chromium molybdenum steels within the tensile strength range 300 N/mm2 to 700 N/mm2 and in the hot-rolled, hot-rolled and normalized or annealed conditions, with or without tempering. These conversions are not applicable to: a) cold reduced steels; b) quenched and tempered steels; c) austenitic steels. These conversions are not applicable when the gauge length exceeds or where the width to thickness ratio of the test piece exceeds 20.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
