When it comes to 304 stainless steel vs. 316 stainless steel, while both are good for corrosion resistance, strength, welding, and heat resistance, 316 stainless steel gets the slight edge in all these categories due to variation in alloying elements. SUS304には注意点もあります。例えば、塩水や酸性の溶液に長時間浸けると、腐食の可能性があります。また、表面の傷や汚れが付着すると、耐食性が低下することもあります。そのため、定期的なメンテナンスや清掃が必要です。 SS 304 stainless steel physical properties are listed in the table below such as density, melting point, specific heat, electrical resistivity, elastic modulus (modulus of elasticity), thermal conductivity, and coefficient of thermal expansion (CTE). SUS 304 stainless steel has good weldability and can be welded by the usual welding method without heat treatment before welding. AISI 304 stainless steel has excellent corrosion resistance in mild atmosphere and fresh water, and even the surface will not rust. But it’s not resistant to halide (such as chloride, fluoride, etc.) corrosion, because the halide can easily penetrate the passive film and make stainless steel lose the resistance.

SUS303とSUS304はそれぞれ異なる物理的な特性を持っています。使用する場面や要求される性能に応じて、適切な材料を選ぶことが重要です。 4. SUS304の特徴や用途について詳しく知りたい 4-1.

Therefore, SUS304 is referred to as the mother of many other SUS materials. Grade specification comparison Grade SUS304 stainless steel solution heat treatment is from 1010℃ to 1150℃ in rapid cooling method. WeldingWhen it comes to 316stainless steel, you can expect better corrosion and pitting resistance to chlorides than 304 stainless steel and higher levels of strength at elevated temperatures. This is due in part to the addition of molybdenum. This is what makes it an ideal grade for such applications as pumps, valves, textile and chemical equipment, pulp & paper and marine applications. calculations to minimize rounding error.

In this case, SUS304L with lower carbon content should be selected. Applications

SUS304は、金属加工において広く使われている素材であり、その特性を理解して適切に使用することが重要です。適用範囲や注意点を把握し、安全かつ効果的に利用することが求められます。 3. SUS303とSUS304の違いについて知りたい 3-1. SUS303とSUS304の基本的な特徴の比較 Carbon content has a strong influence on room temperature strength and thus the specified minimum tensile properties of 304L are 5 kilopounds per square inch (34MPa) lower than for 304. However, nitrogen also has a strong influence on room temperature strength and a tiny addition of nitrogen produces 304L with the same tensile strength as 304. Thus, practically all 304L is produced as dual certified 304/304L, meaning it meets the minimum carbon content of 304L and also meets the minimum tensile strength of 304. [13] [ full citation needed] See also [ edit ]In the hot section of the weld, intrinsic corrosion, which is referred to as intergranular corrosion, can occur as stainless steel is being welded. If weldability is a priority for the application, stainless steel 304 is specifically resistant to this certain type of corrosion.
