**1 stainless steel coil

 Summary

**1 is a titanium-stabilised version of **4, used in particular applications within the sensitizing temperature range.  Its resistance to sensitization, coupled with its higher strength at high temperature makes it suitable in application where **4 will become sensitized, or where SX **4L has insufficient hot strength.  It is not subject to weld decay (intergranular corrosion) when exposed to mildly corrosive environments.  However, welded **1 must never be used in highly oxidising environments as it is liable to 'Knife-line' attack.

Typical Applications

**1 is today used almost exclusively for service within the sensitizing temperature range (******0oC).  In welded ambient temperature applications it has been replaced by SX **4L.  Some typical areas of application are: 
                Furnace components. 
                Superheater and afterburner parts. 
                Compensators and expansion bellows.

Typical Properties in the Annealed Condition 
The properties quoted in this publication are typical of mill production  and unless indicated should not be regarded as guaranteed minimum values for specification purposes.

Mechanical Properties at Room Temperature  

Thermal Processing 
1.    Annealing Heat  from ***0 to ***0oC and cool in air.  This ensures maximum ductility of the steel. 

2.    Stress Relieving SX **1 can be stress-relief annealed within the sensitization temperature range 
       ******0oC without carbide precipitation occurring, thus avoiding the possibility of intergranular corrosion. 
3.     Hot working 
        Initial forging and pressing temperature:              ***0  - ***0oC 
        Finishing temperature:
