ASME SA268 TP430 Seamless Stainless Steel Tube UNS S43000 1.4016 Ferritic alloy Tube

 

Grade 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application.

Grade 430F is the free-machining version of this grade, available in bar form for use in automatic screw machines. Grade 434 is the molybdenum bearing version of Grade 430 and has the same useful combination of properties. Its molybdenum addition improves corrosion resistance.

These properties for 430 are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as forgings and bar in their respective specifications. Properties of Grade 430F are specified for bar in ASTM A582.

 

Ferritic stainless steel features high corrosion resistance and oxidation resistance due to its high chromium content, but its mechanical properties and machinability are poor. It is widely applied to acid-resistant structures with little stress and is used as anti-oxidation steel. This steel type can resist the corrosion of atmospheric, nitric acid and saline solution. It features high temperature oxidation resistance and small thermal expansion coefficient. It can be used in nitric acid and food factory equipment, and can also be used to produce parts working at high temperature, such as gas turbine parts.

 

Typical Manufacturing Specifications:
 

ASTM A268

 

ASME SA268

 

Typical applications for 430 grade include:

  • Linings for dish washers
  • Refrigerator cabinet panels
  • Automotive trim
  • Lashing Wire
  • Element Supports
  • Stove trim rings
  • Fasteners
  • Chimney Liners

Heat Treatment

  • Solution Annealing – Heat to 815-845°C, hold for ½ hour per 25mm of thickness, slow furnace cool to 600°C and then quickly air cool. Slow cooling from 540-400°C will cause embrittlement.
  • Sub-Critical anneal – Heat to 760-815°C and then air cool or water quench.
  • This grade is not hardenable by thermal treatment.

Welding

  • Pre-heat at 150-200°C if welding is necessary.
  • Embrittlement in the weld metal and heat affected zone can be relieved by a post-weld anneal at 790-815°C
  • Grain refinement will not occur.

Machining

  • Easier to machine than the standard austenitic grades such as 304.
  • Still a tendency for galling and pick-up on the cutting tool.
  • Bars that have been lightly drawn are easier to machine than those in the annealed condition.
  • Grade 430F, the free machining version of 430, is very much easier to machine.

Fabrication

  • Lower work hardening rate makes bending and forming somewhat easier than for grade 304
  • Lower ductility restricts very severe operations.
  • Severe bends should be made with the bend axis at right angles to the rolling direction.
  • Severe cold heading of 430 wire is possible.

Quality Assurance:


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.
