304 is available in Sheet, Strip, Plate, Tube, Bar (Round), Rod, Rings, Forgings.

Type 304 is a variation of the basic 18-8 grade, Type 304, with a higher chromium and lower carbon content. Lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In many instances, it can be used in the ”as-welded“ condition, while Type 304 must be annealed in order to retain adequate corrosion resistance.

Type 304L is an extra low-carbon variation of Type 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the ”as-welded“ condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than Type 304.

Stainless Steel 347 (AMS 5512/AMS 5646) UNS S30347 Werkstoff 1.4544/1.4546/1.4550 :
Alloy 347 is a chromium nickel stainless steel which has been modified by the addition of columbium and tantalum. The main advantage of this is an excellent resistance to intergranular corrosion which is common to other austenitic stainless steels following exposure to temperatures of 800° to 1500°F. Type 347 has about the same general corrosion resistance as Type 302.

Type 347 is generally used where corrosive conditions are severe, such as harsh steel exhaust stacks, manifolds and ring collectors. Type 347 is also used for heavy welded assemblies which cannot be annealed after welding or where the operating conditions cause exposure within the temperature range between 800° to 1500°F.

Applications:

• Typical applications include:
• Rolling element bearings
• Valve seats
• High quality knife blades
• Surgical instruments
• Chisels

Heat Treatment:

• Annealing – Full anneal – 850-900°C, slow furnace cool to about 600°C and then air cool. Sub-critical Annealing – 735-785°C and slow furnace cool.
• Hardening – Heat to 1010-1065°C, followed by quenching in warm oil or air. Oil quenching is necessary for heavy sections. Immediately temper at 150-370°C to obtain a wide variety of hardness values and mechanical properties as indicated in the accompanying table.
• Tempering in the range 425-565°C is to be avoided because of reduced impact resistance and corrosion resistance. Tempering in the range 590-675°C results in lower hardness (the product become machinable) and high impact resistance.

Welding:-If welding is necessary pre-heat at 250°C and follow welding with a full anneal. Grade 420 filler will give a high hardness weld (although not as high as the 440C), but 309 or 310 will produce soft welds with higher ductility.
