3 Bars: 5-50 mm Dimensions-tolerances Drawn material: ISO h9 (DIN 671) Ground material: ISO h9/h8/h7/h6 (DIN 670/671/59360/59361) The above mentioned tolences are RASCH standards. Qualities: Our standard qualities in stainless steel correspond to following standards: RASCH DIN AISI SIS BS DIN ASTMA MNC 900 BS /SAE J 405 RASIMA 304 W S15 RRS 316 W S31 RASIMA 303 W S31 RRS304L 304L S11 RASIMA 316L 316L Specifications: Length: St/C drawn: 6 m Free-cutting steel: 3 m Stainless steel: Dia mm 3m & 4 m Dia mm 3m Other lenghts according to arrangement In case the tolerance of lenght is not specified in the order the bars are automatically drawn according to:

(mm) Lenght (mm) Tol / +2 mm / +4 mm Corner radius: The corner radius of square mat. is app. 0,2 mm. If size of the bundles is not specified, the material will automatically be delivered as follows: Bars: 3 m- 500 kg 4 m- 500 kg 6 m kg (or 500 kg) If the marking is not stated in the order the standard marking will be as follows: All bundles or coils are labelled showing: Company name and adress Charge no. Quality = steel description Profile Dimension and tolerance Weight Unless something else is stated in the order the quantity tolerance is +/- 10% If the surface roughness is not stated in the order the material will automatically be delivered as follows: Ground bars: d 5 <= 50mm max Ra= 1,0 µm d > 50mm max Ra= 1,6 µm Others: d <= 100mm max Ra= 16,0 µm d >= 100mm max Ra= 25,0 µm

5 If nothing else is stated in the order, the straightness will be as follows: Ground bars: max 0,5 mm measured per m.* Normal straightened bar: Round: d<8,0 mm max 1,0 mm measured per m. 8,0 <= d <= 100,0mm max 0,5 mm measured per m.* Square & Hexagon: max 2,0 mm measured per m. Spc. straight. bar max 0,5 mm measured per m* * apply to use of a measuring instrument with support bobbins placed with a distance of app 1 meter from one end of the bar to another. D is the diameter of the bar measured in mm. If nothing else is stated in the order, the roundness of the bars will automatically be as follows: Ground bars: max 33% of the tolerance width Other bars: max 50% of the tolerance width Wire: within of the tolerance width Crack detection is executed according to Eddy current and only when required. If nothing else is stated the bars are checked visually. The packing is automatically as follows when nothing else is stated in the order: Bright drawn: immersed in RBO 30 LS rustprotective oil. Stainless: packed in fibre tissue with plastic bags on the ends. Ground h6 & h7: packed in wooden boxes with layers of fibre tissue. d > 20 is mounted with distance rings. Coils: Rings: packed in tightened plastic. wrapped in crepe paper. Other methods of packing If stated in the order the following methods of packing can be put into use: Oil paper / fibre tissue wooden cases Delivery in steel frame belonging to the customer. As for stainless steel every single bundle can be packed in Lamiflex and layered with fibre tissue. Certificates

6 Fr. RASCH receives certificates on all raw material and by checking and examining the material in our laboratory, RASCH is able to issue certificates. Following certificates can be issued: DS/EN : Containing information of chemical values. DS/EN B: Containing information of chemical and mechanical values. Free-cutting steel in round and hexagon in lenght of 3 and 4 m is chamfered in both ends in the sizes mm. Further round free cutting steel in lenght of 3-4 m in the sizes mm will be delivered with one end faced and hexagon free cutting steel in lenght of 3-4 m in the sizes mm will be delivered with one end faced. Chamfering angle 45º.
