SECTION 7: STAINLESS STEEL BAR (ROUND, FLAT, ANGLES, SECTIONS & WIRE)
Improved machinability bar
Atlas Steels distributes “Improved Machinability” (IM) stainless steel bar.
Improved machinability bar results from a controlled melting process, giving high chipbreaking properties and providing a self-lubricating quality through the processing of
machining.
Range of IM
Grades
• 303, 304/304L and 316/316L round bar, 4.76 to 101.6mm.
• 316/316L round bar, 101.6 to 304.8mm.
• 303 and 316/316L hex bar, 13.34 to 57.15mm.
• 316L – hollow bar.
The benefits
1
• Improved machinability.
• Increased cutting speeds.
• Lower unit cost of production.
• Increased tool life.
• Lower production power
requirements.
• Consistent machinability.
• Chemical composition within ASTM standards.
• Properties the same as commercial grades of
stainless steel
– corrosion resistance
– mechanical properties
– weldability
– formability.
• Improved drilling and tapping characteristics.
• Improved product surface finish.
IM grades will reduce wear on tools and extend tool life
Highly abrasive inclusions which damage tools are excluded in the IM
manufacturing steel melt process.
There is a decrease in flank wear and crater wear of carbide tooling which results in:
• less dismounting and reassembling of tools;
• less adjustment time; and
• a noticeable improvement in the life of cutting tools.
Atlas Steel distributes Ugima “Improved Machinability” grades as its main product but
also other generic brands are available.

Ugima will enable higher cutting speeds
Ugima belongs to a new generation of steels and to benefit fully from its unique
characteristics a minor modification is required to cutting conditions. In particular,
it is necessary to increase cutting speeds.

Common stainless steel bar specifications
ASTM A276:
This specification covers hot or cold finished bar except bars for reforging (see spec. A314).
Includes rounds, squares, hexagons, hot rolled or extruded shapes such as angles, flats,
channels and commonly used grades of stainless steel, including ‘improved machinability’.
Free machining grades such as 303 and 416 are not included (see spec. A582/A582M).
ASTM A479M: This specification covers the same sections as ASTM A276, for use in pressure vessel
construction. Also referred to in ASME boiler and pressure vessel code.
ASTM A582M: This specification covers hot or cold finished free-machining stainless steel bar except bars for
forging (see spec. A314). Includes rounds, squares and hexagons in the more commonly used
types of stainless steels designed for optimum machinability and general corrosion and high
temperature service, primarily grades 303 and 416. Stainless steel bars other than the
free-machining types are covered in other specifications.
ASTM A314:
This specification covers stainless steel billets and bars intended only for forging.
ASTM A484M: This specification covers general requirements that apply to stainless steel wrought bars, shapes,
forgings and billets or other semi-finished material (except wire) for forging, under the latest
revision of each ASTM specification.

Description
Super coat (SC)
Non-metallic lubricant coating – standard heading wire coating.
Bare
All coatings removed.
Lime and soap
Subject to prior arrangement.
Spring wire
Common grades of spring wire are 304 and 316. The drawing coating is usually left
on the wire, assisting with spring manufacturing. Special versions of 304 and 316
with a controlled analysis range are manufactured for required tensile strength values.
Spring temper wire has the highest tensile strength of any stainless steel wire
conforming to ASTM A313M and can also be supplied to JIS G4314.
Coating: Standard coating is ‘spring coat’ for spring forming. By arrangement can be
supplied bare to assist with soldering.
Straightened and cut lengths: Spring temper diameter 1.6 to 10mm can be supplied
straightened and in cut bar lengths, with tensile strength specifications of 90% of the
table listed on the next page.
Stress relief: Stress relief of finished springs in the temperature range of approximately
200-400˚C can improve their elastic properties. Higher temperatures will result in
permanent softening and (above approx. 450˚C) carbide precipitation.

Weaving wire
Grades 304, 316 and some 430 are used in a variety of tensile strengths, diameters and
coatings for weaving. Applications in mining and processing, screens and mesh link belts
for mineral processing, heat treatment and in the food industry.
Specific tensile strengths can be produced to the customers’ requirements, generally
1
/4 Hard or 1/2 Hard (usually 900-1100 MPa or 1000-1200 MPa). Cast and Helix may
also be specified.
Flattened wire
Manufactured in a general range of 0.5mm x 5.5mm to 3.18mm x 8mm.
Edges are as rolled (rounded) as edging rolls are not used. Available in most grades.
