PN/H standards for steel materials

خلاصات:

This group of PN standard specifications covers carbon and alloy steels, plates and forgings used in boilers and pressure vessels, high-strength low-alloy steels, heat-treatable steels, sheets and strips. This article contains standards for various types of steel pipes which specify requirements for high-temperature service, and special applications such as fire protection use. Steel casting and high temperature cast steel specifications call out the standard properties for pressure purposes. The group of standards for tool steels, stainless and heat resisting steels is also presented.

Review of PH/N Standards for steel consists of 3 volumes. It contains formally approved PH/N standard classifications, guides, practices, specifications, test methods and terminology and related material such as proposals.

Covers:

The following data is given for each standard: standard number, 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.

With Total Materia finding information about a metal standard specification, its current status and the materials it defines is one click away.

Within seconds it is also possible for you to find related detailed material property data or search equivalent materials starting from the Total Materia standard list.

To get started, click on the standard list button in the menu bar.


By simply selecting a Standard Development Organization (SDO) and/or typing the standard number, you receive immediate results from the multi-lingual database containing over 30,000 standards.

For example, you can review all metal standards from UNI by selecting this SDO from the popup.


The result list consists of over 1400 UNI metal standards. Information includes: standard description, year of last issue, current status (valid, replaced, etc.) and a hot link to the materials defined by this standard.


By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard.


From the list of materials, you can review detailed properties and equivalents of each material.


For you’re a chance to take a test drive of the Total Materia database, we invite you to join a community of over 150,000 registered users through the Total Materia Free Demo.
