1) Amerika Serikat
a) ASTM ( American Society for Testing Materials )
o Strogen Steel (H3 9M-94)
o High Strength Low alloy Structure Steel (H2 42M-93a)
o Low and Intermediate tensile Strength carbon silicon, steel plate for machine pane and general construction (A 284M-38)
o High Steel Strength. Quenhead and Temporal alloy steel plate euatable for andirum (A 514-94m)
o Structural Steel mide 290 MPa minimum Yield point (BMM) maximum
o High Strongth Low alloy alambium vanadium steel of structural quality (43,72m-94a)
o Structural carbon steel plate of improved longers (AS 37M-93a)
o High Strength Low alloy Structural Steel 345 MPa minimum yield point 100 mm thickness (AS 88M-94a)
o Normalized high Strength Low alloy Structural Steel (A633-94a)
o Low carbonate hardening, nikel copped evanium monodin, corombium and nikel copper columbion allow steel (A710M-94)
o Hot road stuktural steel high Strength Low alloy plate with improved in ability (A 610 M-93a)
o Quenhead and tempered carbon steel plates for structural aniration (A 678-94a)
b) AISI (Americal Iron and Steel Institute) and SAE (Society of Automotive Engineers)
Baja menurut standarisasi AISI dan SAE merupakan spesifikasi dengan loxx digunakan untuk paduan yang sangat minimal. Contoh baja AISI, SAE 1445, ini berarti kandungan karbonnya adalah 0,4% dengan paduan uranium (0,4%-1,4%)
c) Menurut UNS (United Numbering System)
Baja menurut standar UNS hampir sama dengan standar AISI dan SAE, hanya saja menggunakan huruf di depan ditambah lima digit untuk jenis tambahan lainnya misalnya baja AISI,SAE A 0,70% UNS menjadi G41070 di mana awalnya G untuk baja karbon paduan rendah.
2) Jepang (JIS = Japan Industrial Standar)
o Rolled Steel for general structural (G 3101-87)
o Rolled Steel for walled structural (G 3106-92)
o Hot Rolled Atmosphetle corrosion resisting steel (G 3128-87)
o Hot Yield Strength Steel plate for walled structural (G 3128-87)
o Superior atmosphere corrosion resistant steel (G 3215-87)
3) Standarisasi Jerman (DIN = Deutsche Industrie Norm.)
o Steel for general structural purposes (17100-80)
o Waldable tine astin steel (17102-83)
4) Standarisasi Perancis (NF)
o Structural Steel (A 35-501-87)
o Structural Steel Imprived atmosphere votection vistance (H 35-502-DA)
