不銹鋼制品用于家居裝修中會給人一種時尚大氣的感覺，而且實用性能很強，受到了眾多家裝消費者的青睞。有不少人有著這樣的疑惑，都說不銹鋼耐熱，可是它有多耐熱呢？
Stainless steel products used in home decoration will give people a sense of fashion atmosphere, and practical performance is very strong, has been favored by many Jiezhuang consumers. There are many people with such doubts, said stainless steel heat-resistant, but it has much heat it?
耐熱性能是指高溫下不銹鋼仍能保持其優良的物理機械性能。不銹鋼中碳的影響：碳在不銹鋼中是強烈形成并穩。定奧氏體且擴大奧氏體區的元素。碳形成奧氏體的能力約為鎳的30倍，碳是一種間隙元素，通過固溶強化可顯著提高奧氏體不銹鋼的強度。碳還可提高奧氏體不銹鋼在高濃氯化物（如42%MgCl2沸騰溶液）中的耐應力耐腐蝕的性能。

Heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties. The effect of carbon in stainless steel: carbon is strongly formed and stable in stainless steel. An element that determines austenite and expands austenite. The ability of carbon to form austenite is about 30 times of that of nickel, and carbon is a kind of interstitial element. The strength of austenitic stainless steel can be obviously improved by solution strengthening. Carbon can also improve the stress resistance and corrosion resistance of austenitic stainless steel in high concentrated chloride (such as 42%MgCl2 boiling solution).
但是，在奧氏體不銹鋼中，碳常常被視為有害元素，這主要是由于在不銹鋼的耐蝕用途中的一些條件下，碳可與鋼中的鉻形成高鉻的Cr23C6型碳化合物從而導致局部鉻的貧化，使鋼的耐蝕性特別是耐晶間腐蝕性能下降。因此60年代以來新發展的鉻鎳奧氏體不銹鋼大都是碳含量小于0.03%或0.02%超低碳型的。
However, in austenitic stainless steel, carbon is often regarded as a harmful element, which is mainly due to some conditions in the use of stainless steel in corrosion resistance, carbon can be formed Cr23C6 type carbon compound high chromium and chromium in steel resulting in local chromium depletion, the corrosion resistance of steel especially resistance to intergranular corrosion drop. Therefore, since 60s, the new development of chromium nickel austenitic stainless steel mostly carbon content less than 0.03% or 0.02%, ultra low carbon type.
可以知道隨著碳含量降低，鋼的晶間腐蝕敏感性降低，當碳含量低于0.02%才具有最明顯的效果，一些實驗珠光還指出，碳還會增大鉻奧氏體不銹鋼的點腐蝕分傾向。由于碳的有害作用，不僅在奧氏體不銹鋼冶煉過和中應按要求控制盡量低的碳含量，而且在隨后的熱，冷加工和熱處理等過程中也在防止不銹鋼表面增碳，且免鉻的碳化物析出。
You can know that with a decrease in the carbon content of steel intergranular corrosion sensitivity decreased, when the carbon content is lower than 0.02% has the most obvious effect, some experimental Pearl also pointed out that the point corrosion of carbon will increase the tendency of chromium austenitic stainless steel. Due to the detrimental effect of carbon, carbon content should be controlled as low as required not only in austenitic stainless steel and smelting, but also in the subsequent heat, to prevent the stainless steel surface carburizing in cold working and heat treatment process, and free of chromium carbide.
