Forming
 Hot Rolled Sheet is used for a wide
range of applications, from simple bends to complex
draws or structural applications that require a
specific strength level. In order to meet all the
customer requirements for this variety of
applications, proper selection of the steel grade and
production processing practices are imperative.
Customer selection of a particular sheet steel to
match the requirements of an application can be a
complex task. This selection involves analyzing
the mechanical properties, type of forming required
(bending, stretching, drawing, hole expansion), type
of joining and surface characteristics. A sheet steel
that forms well in one type of operation may not form
well in another. Many forming operations involve a
combination of several types of deformation. In press
operations, the surface interaction with the tooling
and lubrication is critical and must be considered.
For all these reasons, no one single test can be used
to predict formability. For assistance in
selecting the steel quality for your application,
contact your local U. S. Steel Sales Office for
customer technical service.

Welding
 Hot Rolled Sheet is readily
weldable using either arc or electrical resistance
methods. A welding procedure must be utilized
that is compatible with the chemical composition of
the sheet and the in-service requirements of the
final product.
In arc welding, proper joint design, piece fit-up and
electrode selection are critical factors in obtaining
optimum welds. For resistance welding, specific
studies may be required to determine the proper
welding parameters needed for acceptable welds.
The ability to obtain acceptable weld integrity will
be affected by the steel composition, cleanliness,
thickness, welding current and cycle time.
 Painting
Hot rolled products are available in a surface
suitable for satisfactory paint adhesion. As in
all painting applications, suitable surface
preparation and pre-paint treatments must be selected
for the specific application.
