316S33（1.4436）不锈钢是在316的基础上加入了氢，但碳含量处于其的上限，多用于热强性能较不含钼钢要求

更高的耐热用途，具有良好的加工性能、焊接性能，高温抗氧化性能。

316S33 (1.4436) stainless steel is added with hydrogen on the basis of 316, but the carbon content is at its upper limit, which is mostly used for the requirements of thermal strength properties rather than molybdenum containing steel

Higher heat resistance, good processing performance, welding performance, high temperature oxidation resistance.
