| | | Mechanical Properties Static Strength | | |
| | | The Sandvik 1150SM belt grade is made of low carbon, martensitic stainless steel of type 15-7 PH and is characterised by: • Good static strength • Very good fatigue strength • Good corrosion resistance • Good wear resistance • Excellent repairability Sandvik 1150SM is a high strength steel with good mechanical properties. This, in combination with good corrosion resistance, makes it the ideal choice for a wide range of applications. Another advantage is that it is easy to repair. | | |

Sandvik 1150SM should not be exposed for prolonged periods (a few hours) to temperatures exceeding 250°C (480°F) as a change (increase) in strength due to precipitation hardening takes place at high temperatures. Hence the following recommendation: If an operation temperature of or above 250°C (480 °F) is considered, your local Sandvik office should be contacted for technical assistance. | | |

| | | Forms of Supply The belts are, as standard, delivered with a mill finish and have well-rounded edges. If required practically any surface finish can be supplied. Perforated belts are also available. The belts are levelled and straightened to obtain optimal flatness and straightness. The belts can be supplied in open lengths, with the ends prepared for brazing on site, or in endless condition with a welded joint. For tracking, the belts can be provided with V-ropes, either rubber or in the form of a specially designed steel spiral. If required, the product side of the belt can be fitted with retaining strips to keep the conveyed material on the belt or with transverse flights to prevent material from sliding backwards when the belt is steeply inclined. Different tolerance grades are available to ensure that the best belt can be selected from an economic point of view. | | |
| | | |
| | | Dynamic Strength The fatigue limit is defined as the reverse bending stress at which 50% of the test specimen withstand a minimum of 2x106 load cycles. These values refer to 20°C (68 °F), a normal dry atmosphere and standard prepared specimen. The fatigue limit for the parent material is approximately ± 500 MPa (73 ksi). | | |
