柴油机气阀专业厂——德国的Marki-sches工厂生产的镍铬钛耐热合金排气阀已经被Sulzer兄弟有限公司的RTA系列4缸到12缸、直列式两冲程柴油发动机(125—1607L/cyl)采用。Sulzer公司预期这种排气阀的使用寿命能达到3000到4000小时。镍铬钛合金排气阀,其材质是一种高铬含量的镍基合金,被广泛地用于四冲程中速柴油机上。长期试验表明,镍铬钦合金具有良好的热性能和机械性能,它抗腐蚀,耐磨损,耐热裂以及防止发生窜气,造成阀头断
Diesel valve professional factory - Germany’s Marki-sches plant production of nickel-chromium titanium heat-resistant alloy exhaust valve has been Sulzer Brothers Limited RTA series 4 to 12 cylinder, inline two-stroke diesel engine (125-1607L / cyl. Sulzer expects the life of this exhaust valve to reach 3,000 to 4,000 hours. Nickel-chromium titanium exhaust valve, the material is a high chromium content of nickel-based alloy, is widely used in four-stroke medium-speed diesel engine. Long-term tests show that the nickel-chrome alloy has good thermal and mechanical properties, it is corrosion-resistant, wear-resistant, thermal cracking and to prevent blow-by gas, causing the valve head off
