热交换器正常工作温度达1000°F(约283℃)时,用不锈钢制成的螺栓却生锈了!这是为什么呢?原来,在较高温度时,热循环会使某些不锈钢变成非不锈钢。所以选择紧固件材料上一定要慎重,以免发生意外。——MC编者按
Why? With heat exchangers, bolts made of stainless steel rust at normal operating temperatures up to 1000 ° F (about 283 ° C). It turns out that at higher temperatures thermal cycling can cause some stainless steel to become Non-stainless steel. So choose the fastener material must be careful to avoid accidents. - Editor’s Note
