I. Four Major Differences between Stainless Steel 310 and 310S:
After delving into the similarities between stainless steel 310 and 310S, we turn to the key differences between them. These two types of stainless steel both demonstrate their unique characteristics in multiple aspects, and these differences are crucial for the selection and application of these two materials. So, in what aspects exactly are the differences? Next, we will reveal these differences one by one and take you on a deep dive into the unique features of these two types of stainless steel.
Ii. Differences in Chemical Composition Content:
There are significant differences in chemical composition between stainless steel 310 and 310S. The content of each element in these two types of stainless steel is different, and this key distinction directly affects their performance and application range.
The chemical composition content of stainless steel 310 is as follows: The content of carbon (C) does not exceed 0.25%, that of silicon (Si) does not exceed 1.50%, that of manganese (Mn) does not exceed 2.00%, that of phosphorus (P) does not exceed 0.045%, that of sulfur (S) does not exceed 0.03%, and that of chromium (Cr) is between 24.0% and 26.0%. The content of nickel (Ni) ranges from 19.0% to 22.0%.
2. The chemical composition content of stainless steel 310S is stipulated as: The content of carbon (C) shall not exceed 0.08%, that of silicon (Si) shall not exceed 1.50%, that of manganese (Mn) shall not exceed 2.00%, that of phosphorus (P) shall not exceed 0.035%, that of sulfur (S) shall not exceed 0.03%, and that of nickel (Ni) shall be between 19.0% and 22.0%. The content of chromium (Cr) ranges from 24.0% to 26.0%. These component standards collectively constitute the basic chemical properties of stainless steel 310 and 310S.
Ii. Differences in Definitions between Stainless Steel 310 and 310S:
Although both stainless steel 310 and 310S belong to the stainless steel series, they differ in chemical composition and thus possess distinct properties and applications. Specifically, 310S is a product that has undergone composition optimization based on 310. It has a lower carbon content and stricter phosphorus and sulfur content, thus demonstrating superior performance in terms of corrosion resistance and high-temperature strength.
The characteristics of stainless steel 310: As an austenitic chromium-nickel stainless steel, 310 stainless steel demonstrates outstanding oxidation resistance and corrosion resistance due to its high percentage of chromium and nickel. In addition, its excellent creep strength enables it to work continuously and stably in high-temperature environments, thus having good high-temperature resistance.
2、37手游官网310S的特性：310S37手游官网板，作为25Cr-20Ni系的高合金37手游官网，其耐高温氧化性极为出色。它非常适合用于制作各种炉用构件，并能在最高温度达1200℃的环境下连续使用，同时保持其性能不受损。
1、37手游官网310的特性：在高温环境下，37手游官网310展现出卓越的抗氧化性。这得益于其铬元素的局部氧化，该过程会形成一种名为Cr2O3的稳定氧化物。只要金属中的铬含量足够，这种氧化物便能在金属表面连续形成，不仅阻止其他氧化物的生成，还能对金属起到有效的保护作用。
2. Characteristics of stainless steel 310S: Stainless steel 310S also performs well in high-temperature environments, effectively addressing the issue of carbon tool steel being prone to cracking, thereby extending the service life of the tools. Its vacuum degassing refining process ensures the quality stability of the steel. Meanwhile, the excellent hardenability and oil quenching hardenability endow the tool with outstanding toughness and wear resistance, ensuring its long-lasting durability.
