Chronifer Supra material is Manufactured in Rod, Bar and coil

AISI 304 Stainless Steel

 

Corrosion Resistance

It resists rusting, from all atmospheric sources and is recommended for use in connection with foodstuff, sterilizing, most of organic chemicals and dyestuff.  For best results it is recommended that the surface of parts is polished and free from scale, foreign particles.  This is accomplished with passivating.

 

 

Surface Execution

< 2.00mm: cold drawn, polished

>= 2.00mm: cold drawn, ground polished with surface roughness N5

Standard in bars of 3m lengths =/- 50mm

In coils for Escomatic machines (approx 35kg/coil)

 

 

Tolerances

Standard ISO h7 (special sizes and tolerance are in short time available)

 

 

Heat Treatment

For high corrosion resistance and low magnetism, there may be an annealing procedure necessary.  This annealing is only useful after a strong cold working which raised the mechanical resistant

Annealing:  Heat to 1010-1120C (1850-2050F)

Hardening: Cannot be hardened by heat treatment

 

 

Mechanical Properties

Tensile strength at delivery form 720-950 N/mm2

Tensile strength after annealing 540-750 N/mm2

 

 

Welding

Very good for welding, brazing resistance seam welding  and others

 

 

Cutting Rate

20-30m/min (approx value, depending on the lubrication oil, the cutting tools., the form of parts.

 

 

Stock Range

1.00 to 13.00 mm round full material in stock, other dimension on request
