Isahani yicyuma munsi ya ASTM A285 iri mubyiciro bitatu, A, B na C, ikoreshwa cyane ni plaque ya ASTM A285.
Bikaba bikozwe nubwicanyi, igice cyicwa, gifunzwe cyangwa kizengurutse ibyuma byabigenewe.

Umubyimba: 6MM kugeza 300MM,
Ubugari: 1500mm kugeza 4050mm,
Uburebure: 3000mm kugeza 15000mm

Icyiciro cya A285 A Ibigize imiti
Icyiciro	Ikintu Cyiza (%)
	C.	Si	Mn	P.	S.
Icyiciro A285 A.	0.17	0.08-0.45	0.98	0.035	0.035

Carbone ihwanye: Ceq = 【C + Mn / 6+ (Cr + Mo + V) / 5+ (Ni + Cu) / 15】%

Inyandiko zerekanwe:

ASTM Sandards:

A20 / A20M: Ibisabwa muri rusange kubisahani yicyuma cyumuvuduko.

Ibisabwa muri rusange no gutumiza amakuru:

Uburyo bwo gupima no kugerageza uburyo, inzira, kwihanganira ibipimo, ubwinshi, ubuziranenge no gusana inenge, gushyira akamenyetso, gupakira no gutumiza amakuru agomba kubahiriza A20 / A20M.
Usibye kubisabwa byibanze, ibisabwa byinyongera birahari.
Ibiceri bivanwa muri A285 kugeza byaciwe kubisahani.
