| Sulfur (yaasha) | ≤ 0.030% |
| Nitrogen (n) | 0.10 - 0.30% |
| Bir (f) | Isku qiyaasidda |
Waxyaabaha hantida: astaamaha muhiimka ah
253MA(Amm st3015) waxay isku daraan xoog heerkulka heerkulka sare leh caabbinta oksidacation. Tani waxay ka dhigaysaa inay ku habboon tahay codsiyada jawiga aadka u daran, sida foornooyinka iyo is-beddelka kuleylka. Maaddadu waxay leedahay chromium-ka sare iyo niyofel, oo siiya iska caabin heer sare ah oo ah oksidation heerkulka ilaa 1150 ° C (2100 ° F).

Geedi socodka wax soo saarka: farshaxanimada saxnaanta
Soosaarka253ma tuubooyinka birta ee birta ahWaxay raacdaa farsamooyinka wax soo saarka ee ugu dambeeyay si loo hubiyo tayo sare iyo cimri dherer:
- Soosaarka tuubbada aan kala go 'lahayn: Waxaa lagu soo saaray soo-saarista, wareejinta wareejinta, iyo geedi socodka ciriirida si loo abuuro tuubooyin aan kala go 'lahayn oo leh dhumucdii derbiga labiska.
- Geedi socodka shaqada-qabow: Sawirka qabowga ama hanaanka tijaabada ah ayaa loo shaqeeyaa si loo gaaro cabbir sax ah iyo sagxadaha siman.
- Daaweynta kuleylka: Tuubooyinka lagu daweeyo kuleylka heerkulka gaarka ah si kor loogu qaado hantidooda farsamada iyo waxqabadka heerkulka-sare.
- Xadhiga & xaasidnimo: Tuubooyinka waxaa la jeexjeexay si looga saaro filimada qiyaasta iyo filimada oksig ah oo loo soo bandhigo si loo hubiyo iska caabbinta si aad u adkeysato.
Tijaabada iyo kormeerka: Xaqiijinta Tayada
Steel steel ah ayaa raacaysa borotokool adag oo tijaabo ah si loo hubiyo tayada ugu sareysa253ma tuubooyinka birta ee birta ah:
- Falanqaynta Cabbirka kiimikada ee kiimikada: Waxaa lagu xaqiijiyey iyadoo la adeegsanayo farsamooyinka Spechoscopicscopic si loo xaqiijiyo in alerku uu buuxiyo waxyaabaha la cayimay.
- Tijaabada farsamada: Tensile, adkaan, iyo tijaabinta saameynta si loo xaqiijiyo waxqabadka maaddada heerkulka kala duwan.
- Imtixaanka Hydrostatic: Tuubbooyinka waxaa laga baarayaa in lagu qaado dheecaanka cadaadiska si loo hubiyo waxqabadka aan daadanayn.
- Tijaabada aan wax burburin karin (ndt): Waxaa ka mid ah ultrasonic, eddy hadda, iyo dheeal galinta baaritaanka galka si loo ogaado cillado kasta oo gudaha ah ama dusha sare ah.
- Muuqaalka Muuqaalka & Moodhka: Tuun kasta waxaa muuqata in la fiiriyo dhameystirka dusha sare, iyo sax ahaanta cabbirka ayaa laga hubinayaa ka dhanka ah faahfaahinta.
