• Hunhu hwemakanika
◦ Simba guru: Simba rekudhonza σb i825MPa~925MPa, uye mamwe mashoko ari pamusoro pe980MPa. Ine simba rakanaka rekutakura zvinhu uye yakakodzera mamiriro ekumanikidzwa kwakanyanya.
◦ Kupfava kwakanaka: Ine muganho wepamusoro wekupfava, inogona kutsungirira kupfava kukuru kwe elastic isina kupfava zvachose, uye inogona kuchengeta nekuburitsa simba nemazvo.
◦ Kuomarara kwakanyanya: Mushure mekupisa, inogona kusvika HRC50 kana kupfuura, ine simba rekudzivirira kupfeka, yakakodzera mamiriro ekupfekwa.
◦ Kusimba kwakanaka: Kana ikaiswa mumitoro inokandwa, inogona kunwisa simba rakati pasina kutyoka, izvo zvinovandudza kuvimbika uye hupenyu hwebasa mumamiriro ezvinhu akaomarara.
• Hunhu
◦ Kusimba kwakanyanya: Manganese inovandudza zvakanyanya kuomarara, yakakodzera kugadzirwa kwezvitubu nezvikamu zvikuru zvine dhayamita inopfuura 20mm.
◦ Katsika kadiki kekubvisa makabhohaidhiretsi pamusoro: Hunhu hwepamusoro hunogadzikana panguva yekurapwa nekupisa, zvichideredza njodzi yekukundikana nekukurumidza.
◦ Kunzwa kupisa zvakanyanya uye kupfava kwekudzikamisa: Tembiricha yekudzima inofanira kudzorwa zvakasimba, uye tembiricha yekupfava inofanira kudzivirirwa panguva yekudzikamisa.
◦ Kushanda zvakanaka pakugadzirisa: kunogona kugadzirwa nekusungirirwa, kwakakodzera kugadzira zvikamu zvine chimiro chakaoma, asi kutonhora kwepurasitiki kwakaderera.
• Zvinodiwa pakurapa kupisa
◦ Kudzima: Kudzima tembiricha 830℃±20℃, kutonhora kwemafuta.
