Whakataki tauira

He tikanga tere te whakamahana me te whakamahana tinei mō ngā paipa maitai. Ki te whakatauritea ki te whakamahana mura tuku iho, he maha ngā painga: he tino angiangi ngā konganuku o te hanganga whakarewa; ka tere te whakamahana ki te pāmahana austenitic i mua i te tinei ka hangaia he hanganga martensite tino angiangi, ā, i te wā e tinei ana, ka hangaia he hanganga ferrite-pearlite angiangi. Nā te poto o te wā tinei whakamahana, ka puta ngā matūriki carbide iti, ā, ka tohatoha ōrite ki roto i te anga martensite angiangi. He tino painga tēnei hanganga mō ngā anga ātete-waikura.
