Link chains of increased properties


 

Chains of increased grade properties: PW-9 (>900 MPa), C-SUPER (>900 MPa), D-3 (>1000 MPa), D-3 EXTRA (>1050 MPa), E-FASING (>1100 MPa) are  characterized by much higher performance parameters in comparison to chains mentioned in PN and DIN standards. The increased durability and operation strength of the chains is a result of introducing the highest quality steel to the production process. The applied steel is customized, highly optimized – conforming to DIN 17115, PN-92/H-93028 standards, with alloy micro-additions acc. to FASING Technical Specifications. The WO steel and special, multiple heat treatment guarantee to achieve higher, more favourable actual technical and performance parameters in chains. This technology provides an optimal, repetitive hardness distribution in every link, moreover, in the case of PW-9, D-3, D-3 EXTRA, E-FASING grades  it allows obtaining diverse hardness in one single link,  i.e. hard crowns and plasticized legs of lower hardness. It is not recommended to use chains of increased properties, particularly the chains of the highest grade  i.e. D-3 EXTRA and E-FASING in harsh, aggressive environment because of the risk posed by pitting corrosion and friction martensite that lead  to operation failure.

In such cases, we suggest individual chain selection to specific performance conditions. Depending  on the longwall degree of aggressiveness, we advise using various types of protection applied onto the chain surface:

·       preservation with special anti-corrosive lubricant FAS-KBP 50/00/22,

·       preservation with special anti-corrosive oil,

·       hot dip galvanizing FAS-Zn-O,

metallization (inlet protection) FAS-Zn-M.

On the basis of DIN 22252 standard, mechanical properties of round link chains apply to dry, natural black state, which occurs after technological production process. Pursuant to the standard, the chain strength parameters which include protective coatings are decreased ca. 10-20%. This percentage change must be considered when selecting the chain or making calculations. This phenomenon is known as the Rebinder effect.
