SAH Steel Bars

Customized Solutions for the Steel Processing Industry

Stahl nach Maß für die stahlver­arbeitende Industrie

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 40 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.

Areas of application for SAH steel bars

Automotive and Commercial Vehicle Industry: Components made from SAH steel bars are installed in every European car. These range from gears, connecting rods, and transmission shafts to chassis components like stabilizers, torsion bars, and coil springs, as well as quenched and ground steering racks.

Chain Producing Industry:
SAH steel bars are used to manufacture high-quality round steel chains, hooks, or shackles.

Tool Industry:
SAH steel bars are highly valued in the production of drills, chisels, and tools like socket wrenches or double-ended spanners.

Wind Power Projects:
SAH steel bars serves as transmission shafts or in the form of quenched bolt screws in wind turbines.

Oil Industry:
SAH case-hardening and quenched steels are used to produce pump rods, among other applications.

Agricultural Technology:
SAH steel bars are used to manufacture highly stressed tools for soil cultivation. Bearing steels and free-cutting steels are also utilized in engine and transmission components.

In all these industries, our quality is trusted as the foundation for the safety and long service life of our customers’ products.

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 tons) 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 tons)  for bright steel can amount a ma­xi­mum of 500 ppm.
