Steel PK11SP (Mat.No. 1.4541, DIN X6CrNiTi18-10, AISI 321)
Designation by Standards

Brand Name        Ravne No.        Mat. No.        DIN        EN        AISI
PK11SP        914        1.4541        X6CrNiTi18-10        X6CrNiTi1810        321

Chemical Composition (in weight %)

C        Si        Mn        Cr        Mo        Ni        V        W        Others
max. 0.08        max. 1.00        max. 2.00        18.00        -        10.50        -        -        min. Ti=5 x C x 0.7

Description
The key feature of 321 stainless is its resistance to intergranular corrosion. It employs titanium as a stabilizing element against chromium carbide formation. This alloy also exhibits strength characteristics superior to those of 304 stainless.

Applications
Jet engine parts, furnace heat treated parts, expansion joints, turbo superchargers, oil refiners, exhaust manifolds and high temperature chemical production equipment.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 203, 186 (200oC), 172(400oC)
Density [g/cm3]: 7.9
Thermal conductivity [W/m.K]: 14.6
Electric resistivity [Ohm mm2/m]: 0.73
Specific heat capacity[J/g.K]: 0.502

Coefficient of Linear Thermal Expansion 10-6 oC-1

20-100oC        20-200oC        20-300oC        20-400oC        20-500oC
16.0        17.0        17.0        18.0        18.0

Hardening
Harden from a temperature of 1020-1100oC followed by water or air quenching. Structure is austenite with small ferrite component.

Mechanical properties in solution-annealed condition and reistance to intercrystalline corrosion
Hardness: 130-190 HB
0.2 % proof stress: 190 N/mm2
1.0 % proof stress: 225 N/mm2
Tensile strength: 500-700 N/mm2
Elongation: 40% (for d<=160, longit.)
Resistance to interystalline corrosion: yes (in as delivered condition), yes (in sensitised condition)
Note: Sensitisation treatment for 15 min at 700oC with subsequent cooling in air.

Mechanical Properties At Elevated Temperatures

Quenched Condition

Temperature        50oC        100oC        150oC        200oC        250oC        300oC        350oC        400oC
0.2 % proof stress in N/mm2        190        176        167        157        147        136        130        124

Forging
Hot forming temperature: 1150-850oC.

Machinability
Excellent speeds and feeds are capable with this material. The addition of sulfur causes a very brittle chip. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series.

Corrosion Resistance
Resistant to a variety of organic and inorganic chemicals, fresh water and atmospheric corrosion.

Welding
Although not recommended, welding may be performed if low temperatures are employed. Recommended filler metal is AWS E/ER312. At high temperature, the sulfur in 303 tends to precipitate at the weld boundary resulting in weak and brittle joints.

Cold working
Minor deformation is possible with this alloy, although it is not its strong point. Type 303 Se is superior in this aspect.
