Appendix 3 [Description] of materials list (materials with high frequency of use)
Highly alloyed steel [Specific examples] *This table is written in JIS(Japanese Industrial Standards)
・JIS G4305：Stainless steel (SUS-Series)
・JISZ2550：Sintered metal materials (P,SMF,SMK-Series)
・JIS G4312,JIS G5122,etc：Heat-resistant steel (SUH-Series)[Description]
An alloy steel means modified steel or steel to which more than one alloy element is added in order to obtain characteristics
for specific purposes. Specifically, a high-alloy steel means an alloy steel which contains alloy elements over 10 weightpercent(wt%) in total.
So-called stainless steel is a high-alloy steel with iron as the main constituent to which approximately 10.5(wt)%(JIS G0203
simply defined based on 10.5%) or more of chrome is added.
ISO uses mass percent (mass%), which is essentially the same as weight percent (wt%). Since AIS and other data formats inother Industries use wt%, wt% is used for expressing percentages.
