SandVik Bioline 1RK91醫(yī)用不銹鋼

山特維克BIOLINE 1RK91是專門為需要高度度的結(jié)合作為交付的條件，較終產(chǎn)品和高成形性良好的延展性的應(yīng)用而設(shè)計(jì)的沉淀硬化不銹鋼。較終產(chǎn)品老化后強(qiáng)度加大。

一般的特點(diǎn)，可以說是一個(gè)普通的奧氏體不銹鋼和低合金鐵素體鋼的性能相結(jié)合。例如，彈性模量，機(jī)械性能和熱膨脹系數(shù)與鐵素體鋼（如低合金碳素鋼或鉻鋼），而耐腐蝕奧氏體不銹鋼相媲美。

• 優(yōu)良的機(jī)械性能非常高的拉伸強(qiáng)度和硬度水平可達(dá)到

• 保留力學(xué)性能，在溫度上升到至少400℃（750℉）

• 很好的松弛性能

• 良好的焊接性

Sadvik Bioline 1RK91 is a precipitation hardening stainless steel specifically designed for applications requiring high strength combined with good ductility in the final product and high formability in the as-delivered condition. The strength is increased after ageing of the final product.

The characteristics in general can be said to be a combination of properties of ordinary austenitic stainless and low alloyed ferritic steels. For example, elastic modulus, mechanical properties and thermal expansion are comparable to ferritic steels (such as low alloyed carbon steels or chromium steels) while corrosion resistance is more comparable to austenitic stainless steels.
