Technological properties of grade steel: 35S20 1.0726 Hardness and heat treatment specification of steel grade: 35S20 1.0726 EN 10277-3: 2008 Bright steel products. Technical delivery conditions. Free-cutting steels EN 10087: 1999 Free cutting steels. Technical delivery conditions for semi-finished products, hot rolled bars and rods.
For precision ground bar and hard chromed bar, the maximum straightness deviation should be less than 0.30mm over one (1) metre. Other tolerances may be agreed, subject to enquiry. Bright steel bar can exhibit "memory", particularly in harder grades eg. straightened bar produced from coiled feed can tend to curl up slowly in storage.

* Annealed Extracted from BHP Free Machining Steels Brochure May 1970. 8.5 Cold Forming The degree to which bright bar can be cold formed by processes such as bending, flattening, crimping or swaging is mainly determined by the ductility of the material. The higher the carbon the less ductile. Cold drawn is generally less ductile than hot rolled.

Tool Life Behaviour | SpringerLink
When machining tool steels in a normalized or soft-annealed state, the increased adhesion tendency and associated growth of built-up edges have a negative effect on surface quality. This can be partially remedied by means of a quenching and tempering to a higher strength.
