Double yield strength

The yield strength of #1.4462 stainless steel is twice as high as the one of #316 and #304 stainless steel.

(EN 10088 / ASTM A240)

High ductility

High ductility makes all #1.4462 stainless steel anchor hollow bars achieve Elongation Agt ≥ 5%.

(DIN EN 10080 / DIN 488).

Superior anti corrosion quality

Extremely high corrosion due to unique quality of high Ni & Cr and low carbon content (EN 10088/1–2005)

Cr: 21-23 / Ni: 4.5-6.5 / C: ≤ 0.03 (%)

Lighter unit weight and lower cost

Double yield strength helps #1.4462 stainless steel to be designed with lighter unit weight and lower cost.

TR thread, 

T thread can connect R thtead

Unique TR thread design noly only achieves the crack widths to stay below the maximum permissible width of 0.1mm (DIN EN 10080 / DIN 488), but also matches perfectly to all the standard R threads in the market (R32&R38/ ISO 10208, R51/ISO1720).
