TOBspecials

Our TOBspecials brochure showcases our product range for A5 – 1.4571, 1.4529 HCR and 1.4462 DUPLEX special materials.

TOBproducts  A5 | 1.4571

Are you interested in our connecting elements in 1.4571 and A5? DIBt, the technical authority in Germany in
the construction sector, requires 1.4571 for corrosion resistance class III. This material is used wherever connecting elements made of A4 or A5 stainless steel are required. 1.4571 is used in construction projects where freshwater or rainwater contact takes place.

TOBproducts  D6 | 1.4462 DUPLEX

You can find our product range for 1.4462 material here. 1.4462 material (DUPLEX) is prescribed by the DIBt
for corrosion resistance class IV. The DUPLEX material is used in construction projects in an environment that contains chloride or saline water.

TOBproducts  A8 | 1.4529 HCR (1.4539 HCR)

Obtain an overview of our products containing material 1.4529 HCR. 1.4529 (HCR) material represents “the king” of highly corrosion resistant steels and is used in projects in corrosion resistance class V, which is referred to as “very strong”. This applies to connecting elements in environments containing a lot of chlorine, such that of swimming pool construction. It is also used in environments where high sulphur dioxide levels exist, such as in road tunnels and urban car parks.
