17-4 ph vs 316
機械部品にはいろいろありますが、その多くは熱処理によって機械的性質を制御されています。さらに表面処理を適用すれば、表面には新たな特性が追加されて高性能・長寿命化は当然であり、付加価値も飛躍的に高まります。
The properties of precipitation hardenable stainless steels could be Improved by a collection of suitable heat treating parameters. The usage of Alternative dealing with on your own or solution managing followed by precipitation age hardening is usually made use of with precipitation hardenable stainless steels.
XTJ is a number one OEM Producer that is dedicated to providing 1-stop manufacturing options of Machining 6061 Aluminum from prototype to generation. We have been proud for being an ISO 9001 Qualified procedure top quality management corporation and we are identified to build value in each and every customer relationship.
Speaking of heat treatments like quenching, tempering, and annealing all have diverse effects within the properties of 630 stainless steel.
630 stainless steel calls for equally Option treatment and aging (precipitation hardening) to realize its full mechanical properties, a essential distinction from other martensitic stainless steels.

最初の固溶化熱処理後の組織はオーステナイトです。そのままでは素地が軟らかいのでマルテンサイトへ変態させ、その後析出硬化処理を行い更に硬くします。
機械構造用鋼の持っている最高の特性を発揮させるためには、理想的には焼入れによって完全なマルテンサイト組織にすることです。

630 stainless steel is magnetic in the two annealed and hardened states because of its martensitic framework. Its magnetic reaction is much better in the solution-treated condition but minimizes following aging, rendering it appropriate for apps necessitating average magnetic properties.
破面のミクロ観察は通常走査型電子顕微鏡によって行われています。破壊には結晶粒界に沿って亀裂が進行する粒界破壊と結晶粒内を進行する粒内破壊があります。
Corrosion Resistance: 630 stainless steel exhibits fantastic corrosion resistance in a large range of environments. It resists general atmospheric corrosion and demonstrates enhanced resistance against stress corrosion cracking when aged at temperatures of 550°C or better.
Carbon, Silicon, Manganese, Phosphorus, Sulfur are the main basic things in JIS SUS 630 JIS G4303. Carbon is The key hardening element in steel. Silicon really helps to strengthen the strength. Like manganese, silicon is utilised to maintain the strength of steel for the duration of steel production. Manganese would be the essential austenite stabilizing aspects contribute into the formation of texture construction and enhance the firmness, strength and wear resistance.
