Il Fiat C.R.30 era un aereo da caccia monomotore, monoposto e biplano, prodotto dall'azienda italiana Fiat Aviazione negli anni trenta.

The aircraft was powered by a 600hp (447kW) Fiat A.30 RA Vee piston engine. Two prototypes were entered into an international meeting at Zurich in July 1932 and won the speed circuit contest at average speeds of 340km/h (211 mph) and 330km/h (205 mph).

2021年12月21日 · Calibration: the CR30 is very basic really, no self levelling, and a very basic UI. This is generally crealitys ethos, and what keeps their printers cheap. Also means less to break though, so not all bad.

F30%CrMo材料是法国H·S公司专有技术，该材料铸造工艺性差，制造技术非常复杂，但材料的耐蚀耐磨性能特别优异，代表世界先进水平。 Cr30A是一种双相不锈白口铁，是国内首创。 其金相组织为奥氏体+铁素体+粒状共晶碳化物+二次碳化物。 它的双相基体中含大量易钝化和抗孔蚀性良好的合金铬、钼、铜等元素。 由双相基体赋予材料的耐蚀性。 在含有氯化物100000ppm，PH值为4的70℃硫酸溶液中腐蚀速率为0.5mm/a。 同时，分布于晶界的含铬碳化物和沉淀于基体上的 …
