Zhenjiang Marine set of 9 * 53 mm lashing chain, galvanized chain bundling, bundled marine anchor chain without gear, chain grapple with complete specifications, 6 * 35mm lashing chain, 7 * 35 mm lashing chain ship will dock we went to the purchase of marine Lashing chain, hatch chain, anchor of the moment, we are doing we remember the chain of manufacturers to contact me oh ~~~ Marine Lashing chain use with the process described: (1) Marine Lashing chain commonly used method of heat treatment: annealing, normalizing, quenching and tempering, carburizing, nitriding, carbonitriding, boronizing. Aging treatment artificial aging, natural aging process. Annealing, the workpiece is heated to marine lashing chain Ac3 30-50 degrees, holding a certain time, with the furnace cooled to 500 degrees at cooling in space. Normalizing, heating marine lashing chains or steel to Ac3 Acm above, an operation after removing heat from the furnace in air-cooled. Hardening, the steel is heated to marine lashing chain above Ac3 or Ac1, after holding fast cooling in water or oil, coolant, has been unstable organization. Tempering the quenched steel marine lashing chain reheated to a temperature below Ac1, after cooling to room temperature incubation of the heat treatment process. Natural aging treatment, the workpiece marine lashing chain left at room temperature conditions or prolonged storage of natural aging phenomenon occurs, called natural aging. Artificial aging treatment, the use of the marine lashing chain workpiece is heated to a higher temperature and a shorter time for aging treatment aging treatment, called artificial aging treatment (2). Common Specifications: within dia6mm length 35mm, minimum breaking load 10 tons purposes: for containers, vehicles and other cargo lashing in the shipping process. Material: High-strength steel Finish: polished, black, plastic, galvanized and varnished (paint color specified by the customer).
