XYLAN Coated Bolts, Xylan Coated Bolting, Xylan 1014/1070/1424 Coated Bolts

ASTM A193 / A320 B7, L7, B7M, L7M, A453 Gr 660 Cl A/B/C/D, Zeron 100 FG

Xylan Coated Bolts offer many benefits for offshore service. These include resistance to corrosion and chemical attack, superb subsea visibility, lower maintenance costs and less downtime.
Xylan Coated Bolts have been the first choice of many engineers in the offshore industry for more than 40 years. Xylan Coated Bolts have significantly more bonding resin relative to its content of polytetrafluoroethylene (PTFE) lubricant. This provides a finish that is harder, more abrasion-resistant, glossier and less porous. Friction values remain low and predictable.

  • (A) Values are maximums unless a range or a minimum is indicated. Where ellipses appear in this table, there is no requirement and the element need not be determined or reported. The intentional addition of Bi, Se, Te, and Pb is not permitted.
  • (B) Product Analysis-Individual determinations sometimes vary from the specified limits as shown in the tables. The several determinations of any individual element in a heat may not vary both above and below the specified range. Product variation limits are over for maximums, over or under for ranges, and under for minimums, unless otherwise indicated.
  • (C) Typical steel compositions used for this grade include 4140, 4142, 4145, 4140H, 4142H, and 4145H.
  • (D) For bar sizes over 31/2 in. [90 mm], inclusive, the carbon content may be 0.50 % max. For the B7M grade, a minimum carbon of 0.28 % is permitted, provided that the required tensile properties are met in the section sizes involved, the use of AISI 4130 or 4130H is allowed.
  • (E) Total of soluble and insoluble.
  • (F) Columbium and Niobium are alternate names for element 41 in the Periodic Table of the Elements.
