    • Mo iron is molybdenum and iron alloy. Its main use is in steel*** molybdenum elements as the agent to join. Steel with molybdenum can make the steel h***e unif fine grain organization, and improve its quench-hardening ability of steel, help to eliminate brittleness. In high speed steel ***, molybdenum can replace part of tungsten. Molybdenum alloy elements with the other with together is widely used in the production of stainless steel, steel, acid resistance to hot steel and steel, and with special physical properties of the alloy. Add in the cast iron molybdenum can increase the strength and wear resistance.

      Mo iron usually adopt melting metal hot method. Mo iron is legal inspection goods. Main origin h***e jilin, hebei, jiangsu, henan, liaoning, mainly export to the United States, the Netherlands, Germany, etc.

      1. The brand and chemical composition

      Press GB3649-87 regulations, molybdenum iron molybdenum and impurity content according to the different divided into three grades, the chemical composition should comply with the provisions of the table, such as the buyer to list elements h***e special requirements, we can separately by both the supply and the demand. Buyer"s requirement, can provide consultation list elements other than the measured data.

      2. Physical state

      Products to block delivery, piece of degree range of 10 to 150 mm, 10 x 10 mm below, shall not exceed the total size of he***y 5%, allowing a ***all piece of degrees in one direction maximum size is *** mm.

      3. Inspection standard

      (1) the quality inspection and acceptance. The quality of the products should be consistent with the inspection and acceptance of GB/T3650-95 "acceptance, packaging, storage and transportation ferroalloy, signs and quality certificate general provisions of the requirements of the".

      (2) of group. Products to a the furnace for a batch of delivery or by both the supply and the demand according to the furnace of group agreed, each product group with the highest or lowest molybdenum content and ***erage sample containing molybdenum amount shall not exceed 3% of the difference.

      (3) sampling. Chemical analysis of the sample should be taken with GB/T4010-94 "ferroalloy with samples taken chemical analysis and preparation of.

      (4) sample preparation. Chemical analysis of samples with the preparation of GB/T4010-94 "ferroalloy chemical analysis and system with samples taken for" carry on.

      (5) chemical analysis method. Corresponding to the following standards each element inspection: GB5059 1-85 8-hydroxyl KuiLin weight method to determine the molybdenum amount; GB5059.2-85 malachite green spectrophotometry antimony quantity; GB5059.3-85 atomic absorption spectrophotometry quantity copper; --88 GB5059.4 predicating method for the determination of zion; GB5059.5-86 weight method for the determination of silicon; GB5059.6-86 molybdenum blu-ray degree method for the determination of phosphorus; GB5059.7-88 infrared absorption spectrometry carbon; GB5059.8-88 coulomb method to determine the carbon; GB5059.9-88 of the infrared absorption method for the determination of sulfur; GB5059.10-88 combustion technique of potassium titration method of sulfur.

      4. Packaging, storage and transportation, signs and quality certificate

      (1) the product USES the iron bucket packaging, 100 kg net weight a barrel, such as the buyer to packaging h***e special requirements, we can both the supply and the demand by negotiation.
