439 Stainless Steel UNS S43035 Ferritic Steel Tube Annealed & Pickled

 

 

(Chromium content 17.0 min, 19.O max.) A stabilized FERRITIC stainless steel with a higher Chromium content than T409 which offers improved corrosion resistance. Available in Cold Rolled 2B or 2D surface finishes. End users include manufacturers of Automotive Exhaust components. Gauges range from .015, to .187. 439 is available in dual-stabilized or titanium-only stabilized versions of which either version performs equally in all environments.

 

Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. It can be used in certain chemical applications due to its resistance to nitric acid.

Applications
 
439 is the perfect grade stainless steel to be used in automotive applications where visual appeal is not a top priority. For this reason and for its durability to gas corrosion, 439 is most commonly used in truck exhaust systems, agricultural equipment, and heat and gas turbine exhaust silencers.
 

 

Typical Manufacturing Specifications:
 
ASTM A268
 
ASME SA268
 

Composition:

  • Carbon: 0.025 max
  • Manganese: 0.50
  • Silicon: 0.75
  • Chromium: 17.00 - 19.00
  • Nickel: 0.50
  • Titanium: ≥ 0.20+4(C+N)min - 0.50 max
  • Iron: Balance

Quality Assurance:

 

Heat Treatments: Type 439 is not hardenable by heat treatment

  • Annealing:
  • Heat slowly to 1450 -1600°F (790 - 871°C), quickly cool. Slow cooling produces less desirable impact transition behavior. Ferritic stainless steels containing more than about 12% chromium have a susceptibility to a phenomenon known as 885°F (475°C) embrittlement. This embrittlement is observed as a degradation of impact properties at room temperature resulting from very long exposures in the temperature range of 700 to 1000°F (371 to 537°C). If service temperatures are cycling through this range, exposure above, about 1050°F (565°C), restores the room temperature toughness properties. When there have been long dwell times near 885°F (475°C), service temperatures that cycle above, about 1050°F (565°C), are beneficial rather than detrimental.

 
Spezilla's seamless bright annealed stainless steel tubes are produced acc. to the following process and inspection to assure our quality:
1. Chemical Composition Analysis Test With 100% PMI.
2. Solution Annealing / Bright Annealed.
3. 100% Hydrostatic Test and 100% Eddy Current Test
4. Mechanical Tests includes Tension Test, Flattening Test, Flaring Test, Hardness Test.
5. Impact Test subject to Standard request.
6. Grain Size Test and Intergranular Corrosion Test.
7. Visual Test and Endoscope Test for Surface Quality Test
