Product Description:

It is a precipitation hardening type of high strength stainless steel. It has excellent corrosion resistance equivalent to that of austenitic stainless steels, and also provides high strength equivalent to chromium stainless steels which have a quench-hardening capacity.

• Outside Diameter21.3mm
• Circular hollow sections up to 1.65mm - 7.47mm

Advantages of Seamless Steel Tubes:

• Excellent formability
• Good weldability
• Excellent corrosion resistance
• Fire resistance
• Toughness at low temperatures

Heat Treatment	It is normally supplied in a solution-treated condition. However, in order to obtain the maximum mechanical properties, it is necessary to perform H900 precipitation hardening heat treatment after working. If ductility is required, we recommend using H1150 precipitation hardening heat treatment. In this case, it is possible to perform precipitation hardening heat treatment of the base material, as working is also possible after precipitation hardening. Heat treatment conditions • H900 precipitation hardening: 470~490℃; air cooling • H1150 precipitation hardening: 610~630℃; air cooling
Weldability	Excellent weldability. By various welding methods. The maximum welding efficiency can be obtained by conventional treatment after welding.
Pickling	In pickling of comparatively thick scale after solution treatment or hot working, the methods used with austenitic stainless steels can be used.
Applications	General purpose stainless steel. Provides excellent performance balance while being easy to use. Food equipment, general chemicals, daily necessities.
