Introduction
Stainless steel grade **1 is a commonly available martensitic
stainless with good corrosion resistance and elevated carbon to
allow for cold working to a variety of tempers.It can be
obtained in the 1/*6 hard,1/8 hard,1/4 hard,1/2 hard,3/4 hard and
full hard .
Type **1 provides high strength and good ductility when cold
worked. The grade is essentially non-magnetic when annealed. High
strength and excellent corrosion resistance make Type **1 Stainless
Steel useful for a wide variety of applications. Typical uses
include aircraft structural parts, trailer bodies, diaphragms,
architectural and automotive trim, automobile wheel covers, roof
drainage products, tablewear, storm door frames and conveyor
belts.
Applications
High strength and excellent corrosion resistance make Type **1
Stainless Steel useful for a wide variety of applications.
Some of the typical applications of grade **1 stainless steels are
listed below:
Making rail car structural components
Air frame sections
Highway trailer components
Automotive wheel covers
Wiper blade clips and holders
Stove frames
Screen frames
Toaster springs
Curtain walls
Roof drainage products
Conveyor belts
Variety of industrial applications
Heat Treatment
Solution Treatment(Annealing)-Heat to ********0ºC and cool
rapidly.
Stress Relief Annealing:Heat to ******0ºF(******2ºC),then air
cool.
Use low side of range for intermediate annealing.
This grade cannot be hardened by thermal treatment.
Cold Working
Stainless steel grade **1 and low carbon variants of this grade are
predominantly used as high strength stainless steel .The work
hardening rates of these grade are very high,in the range of
a *4MPa increase per 1% reduction in area of cold work .As
a result of this characteristic high strength can be achieved
from cold rolling and roll forming operations.
In spite of achieving such high strengths,the residual ductility in
the alloy is capable of causing severe cold deformation .The alloy
is non-magnetic in the annealed condition,but shows strong
magnetism when cold worked.
Hardens at high rate,creating a very high strength from cold
rolling and form roll forming.
More difficult to work than other martensitic stainless steels,due
to its high work hardening rate.
Several cold deformation call still occur,due to residual
ductility.
Grade **1 becomes strongly magnetic when cold rolled
Welding
The martensitic class of stainless steels is generally considered
to be weldable by the common fusion and resistance techniques.
Special consideration is required to avoid"hot cracking" by
assuring formation of ferrite in the weld deposit. This particular
alloy is generally considered to have similar weldability than the
most common alloy of this stainless class
Must be annealed for maximum corrosion resistance
Material will lose temper in the heat affected weld zone.
Welding and post weld annealing will both remove high strength
induced by prior cold rolling.
Heat Resistance
Can be exposed continuously without appreciable scaling to
a max of ***0ºF(**1ºC).
Maximum exposure temperature is about ***0ºF(**8ºC),for
intermittent exposure
Has an oxidation weight gain of *0mg/cm2 in 1,**0 hours,in
temperatures over ***0ºF(**1ºC)
Corrosion Resistance
Type**1 in the nature of high corrosion resistance.The best
corrosion resistance is obtained in the cold worked then annealed
condition.When Type**1 is heated or cooled through
a temperature range of *******0ºF(******1ºC)without subsequent
annealing,it may undergo carbide precipitation that may result in
intergranular corrosion.
Formability
Type **1 can be readily formed and drawn.Due to its high
work-hardening rate,intermediate annealing maybe necessary for
severe drawing and forming operations.
DESCRIPTION: **1 is a hardenable martensitic, nickel bearing
grade, which has the best corrosion resistance properties of all
martensitic grades. Due to excellent tensile strengths it is
particularly suited for use in pump shafts, valve stems, outboard
motor drive shafts and other similar applications. Steel carried in
stock is in a pre-hardened and tempered condition ready for
use.
**1 is a high chromium-low nickel high hardenability
Martensitic stainless steel with high strength and good corrosion
resistance, as generally supplied hardened and tempered in the
tensile range **0 - ***0 Mpa (condition T) Brinell range **8
- **2.Characterised by very good corrosion resistance in
general atmospheric corrosive environments, good resistance to mild
marine and industrial atmospheres, resistant to many organic
materials, nitric acid and petroleum products coupled with high
tensile and high yield strength plus excellent toughness in the
hardened and tempered condition.
