* I-manganese yomxholo inokunyuswa nge-0.05% ye-0.01% ye-0.01% ye-0.01% kwi-carbon yomxholo ukuya kuthi ga kwi-1.35%.
** Umxholo we-Niobium, osekwe kwisivumelwano, unokunyuka ukuya kuthi ga kwi-0.05% yohlalutyo olunyibilikayo kunye ne-0.06% yohlalutyo lwemveliso egqityiweyo.
Iimfuno zonyango lobushushu:
I-1. Kuyinyani ngaphezulu kwe-815 ° C.
2. Iqinisekile ngaphezulu kwe-815 ° C, emva koko umsindo.
3. Ishushu iphakathi kwe-845 ne-945 ° C, ipholile kwiziko elingaphezulu kwe-845 ° C (i-tubs engenamthungo kuphela).
I-4. Mackired kwaye emva koko avutshelwe ngokufanayo nge-3.
5. I-DORDED kwaye ivuthiwe ngaphezulu kwe-815 ° C.
Iimfuno zomsebenzi wentsebenzo:
Isivuno seNkundla: ≥240MPA
Amandla angamanqindi: ≥415MPA

Uvavanyo lwempembelelo
Iqondo lobushushu: -45 ° C
Xa i-charpy encinci ye-chardy isetyenziswa kwaye ububanzi be-notch ye-notch bungaphantsi kwe-80% yobubanzi bezinto ezibonakalayo, ubushushu bovavanyo lwempembelelo olusezantsi kufuneka lusetyenziswe njengoko kubalwa kwiTheyibhile 633.

Ukunyamezelana kodonga lwentsimbi yombhobho wentsimbi:
Nasiphi na inqaku aliyi kuba ngaphantsi kwe-12.5% yobukhulu bomhlaba otyunjiweyo. Ukuba ubuncinci bukhulu bobuncinci bayalelwa, akukho ngongoma iya kuba ngaphantsi kunobukhulu obucekeceke.
