SAH steel bars -

customized solutions for the steel processing industry

 

We ma­nu­fac­tu­re al­loy and non-al­loy round steel bars, as well as we are the Eu­ropean mar­ket lea­der in the pro­duc­tion of bars with dia­me­ters of 12 to 14 mm. Tailo­ring to our cust­o­m­er­s’ nee­ds and pre­mi­um qua­li­ty dis­tin­gu­ish our rol­led and bright steel pro­ducts. Our pro­duct ran­ge of mo­re than 2500 alloys of steel enables us to provide perfectly customized solutions for specific compositions.

 

Our pro­duc­tion ran­ge co­vers stan­dard struc­tu­ral steels, quen­ched and tem­pe­red steels, tool steels and spe­cial steels. The ma­nu­fac­tu­ring ran­ge in­clu­des black, shot-blas­ted, pee­led and  polis­hed steel bars, as well as threaded bolts respectively chamfered, center holed and precision ground steel bars in different heat treatment conditions.

Fields of application

 

  • Automotive and commercial vehicle industry: In every European car are components made of SAH steel bars, from gears, piston rods and tem­pe­red and ground stee­ring gear shafts to suspension components such as sta­bi­li­zers, tor­si­on bars and coil springs.
  • Chain producing industry: High quality round steel chains, hooks and shackles were made from SAH steel bars
  • Tool industry: SAH steel bars are highly appreciated in the manufacture of drills, chisels and socket wrenches.
  • Wind power projects: As gear shafts or as quenched tempered threaded bolts SAH steel bars serve in wind power plants.
  • Oil industry: From case hardening steels and steels for quenching and tempering sucker rods will be produced.
  • Agricultural technology: our round steel bars are used to fabricate highly stressed tools for tillage. Even ball and roller bearing steels as well as free-cutting steels were used in motor and gearbox components.

All the­se sec­tors put their trust in the qua­li­ty of our steel pro­ducts to en­su­re their own pro­ducts safe­ty and dura­bi­li­ty.

 

Surface quality classes

 

For the delivery of hot rol­led bars ap­p­lies the DIN EN ISO 9443 . Acc. to part 4.2 "de­si­gna­ti­on" the re­qui­re­ments of the sur­face con­di­ti­on has to be men­tio­ned in the or­der. Due to the tech­ni­cal li­mits of ma­nu­fac­tu­ring and test me­thods the per­mis­si­ble part of in­cor­rect pro­ducts in the ent­i­re de­li­very unit must be fi­xed.

If the or­der as well as the applicable specification do not contain such a definition, SAH confirms “technical crack free”, if material is ordered with 100% crack testing.

If 100 % crack tested ma­te­ri­al is or­de­red, the in­cor­rect part of a delivery (minimum 5) for rol­led steel can amount a ma­xi­mum of 1000 ppm. 

For de­li­ve­ries of bright steel the de­fi­ni­ti­ons of the EN 10277-1 ap­p­lies. The sur­face qua­li­ty clas­ses are fi­xed the­re. 

If the order as well as the applicable specification contains for­mu­la­ti­ons in the sen­se of: "be free of cracks" or "no sur­face de­fects al­lo­wed", then SAH con­firms sur­face qua­li­ty class 4 ac­cor­ding to EN 10277-1 "ma­nu­fac­tu­red tech­ni­cal­ly crack free".

If 100 % crack tested ma­te­ri­al is or­de­red, the in­cor­rect part of a delivery (minimum 5)  for bright steel can amount a ma­xi­mum of 500 ppm.
