AISI

Type 384: Effect of Cold Reduction

on

Tensile Properties. Annealed at 1065

°c

(1950 °F); water quenched.

Specimens

were

9.53-mm (0.375-in.) round, unstraightened and

untempered.

Tests

were conducted using

specimens

machined to English units. Elongation

was

measured

in 50 mm (2 in. ) ;

yield

strength

at

0.2% offset. (Ref 10)

Characteristics. A I S I type

403 is

hardenable (marte

sitic),

chromium stainless steel. This selected quality steel

manufactured for the production of turbine blades and ver

highly stressed parts. It

is

magnetic in all conditions.

T he type 403 alloy may be cold worked by practicnlly n

metbods

of cold forming. Severe forming should

be

follow

by

a

stress relief

to

prevent cracking. The chips formed

i

machining are brittle and stringy. For most application


2/7

3 1 8/ Stainless/Heat-Resisting

material that has been heat treated

to

hardnesses

of

200

to

240 HB , or annealed and cold drawn, is preferred to material

in

the

fully annealed condition. Machinabi lity

of

type 403

is

about 55% of that for free-machining

A I S I

1212.

This stainless steel can be satisfactorily welded, but is sus

ceptible

to

air hardening and crack ing unless the ma teri al

is

preheated to a minimum temperature of 150 °C (300 °F)

prior

to welding. Wh en welding type 403, filler metal type

410 should

be

used.

Type 403 is

adaptable

to

applications where max imum

resistance to corrosion is not required. It is resistant to the

corrosive action

of

the atmosphere, fr esh water and steam,

and the milder acids and alkalis. This grade has

good

scaling

resistance

up to

675

°C

(1250 °F) in continuous s e r v

Scaling becomes excessive above about 760 °C (1400 K

Typical

Uses. Applications

of A I S I

type 403 incl

steam turbine blades and parts;

gas

turbine blades and

engine parts; valve parts; cutler y; fasteners; furnace pa

and bur ners operating below 650 °C (1200 °F) .
