STEELMAX Steel Story

Carbon steel (탄소강), Alloy steel (합금강),
Stainless Steel (스텐), Free-cutting steel (쾌삭강)

Titanium (티타늄), 철강 금속 제품의 비교적 자주 사용하는
DIN EN Steel Number, Steel name, AISI를 비교합니다.

Stainless는 AISI (American Iron and Steel Institute : 미국철강협회) 규격과
ASTM (미국재료시험협회), JIS 표기법, DIN-EN 표기법뿐 아니라

DIN-EN의 Steel Number와 Steel Name까지 나타나고,
비슷하지만 조금씩 다른, 각국, 단체, 협회 규격이 많아,

UNS No. (Unified Numbering System) 표기법을
같이 병기 해, 사용하기도 합니다.

이와 같은 복잡함으로, 철강 금속 자재의 선정, 사용에
상당한 어려움이 있습니다.

※ Carbon Steel
Steel made by alloy iron and carbon of which carbon content
is generally within a range from 0.02% to 2%.
Further, a small amount of silicon, manganese, phosphorus,
sulfur, etc. are usually contained.
For convenience, carbon steel may be sometimes classified as
according to the carbon content or hardness (including strength).
Classification by carbon content : Low carbon steels,
medium carbon steels and high carbon steels.
Classification by hardness : Extra mild steel,
mild steel and hard steel.

※ Alloy steel
A Carbon steel to which is added a definite amount of one or more
elements other than carbon, in order to impart special properties
to the steel so that it can be used for specific purposes.

강의 성질을 향상 시키기 위해, 또는 소정의 성질을 구비 시키기 위해
합금 원소를 1 종 또는 2 종 이상을 합금 시킨 강.

※ Stainless steel
Alloy steels containing chromium 10.5% or more, carbon 1.2%
or less to improve the corrosion resistance.
They are classified into 5 types, which are
martensitic, ferritic, austenitic, austenitic-ferritic and precipitation hardening.
principally according to their structure at ordinary temperature.

※ Free Cutting Steel
Steels to which free cutting property is improved by
individual or combined addition of phosphorus,
sulfur, lead, selenium, tellurium, calcium, etc.
