Last night, an online friend I hadn\u2019t been in touch with for years suddenly reached out to me and asked what the tungsten (W) content of W6 is.<\/p>\n\n\n\n

\u00a0[Explanation: W6 refers to a general-purpose high-speed steel<\/a><\/strong>\u00a0with the alloy composition W6Mo5Cr4V2, abbreviated as 6-5-4-2. It is commonly referred to as W6 (pronounced \u201ctungsten 6\u201d) in everyday language. Other steel grades with this alloy composition include SKH-9<\/strong><\/a>, SKH51, and M2.]<\/p>\n\n\n\n

 I was a bit puzzled. W6 refers to the high-speed steel<\/strong> with the composition W6Mo5Cr4V2, and its tungsten (W) content is 6.0%\u2014there\u2019s no dispute about that.<\/p>\n\n\n\n

 He continued, \u201cI\u2019ve been tricked. The scrap collector who came to our company this time refused to offer a price, claiming that the previous W6 had a tungsten content of 6.0%, but the current W6 is only 4.0%, and some are even just over 3.0%. If we buy it based on the previous 6.0% tungsten content, we\u2019ll lose a fortune.\u201d<\/p>\n\n\n\n

 Oh, so the tungsten content has been reduced. This is what the market calls \u201cnon-standard W6\u201d\u2014that is, W6Mo5Cr4V2 high-speed steel with alloy composition that doesn\u2019t meet specifications. With tungsten prices having tripled this year, they\u2019re skimping on tungsten even more.<\/p>\n\n\n\n

 I\u2019d heard before that non-standard W6 had a tungsten (W) content of 5.0%, but I never expected to see tungsten content as low as 4.0% or even lower now\u2014it just goes to show they\u2019re \u201cmaking progress.\u201d<\/p>\n\n\n\n

 Generally, when the tungsten (W) content drops, the content of the precious element molybdenum (Mo) also decreases accordingly. That\u2019s just how the market works: if you want something cheap, they\u2019ll always find a way to make it cheaper.<\/p>\n\n\n\n

 Hearing this news, my takeaway is that counterfeit products will only get more and more counterfeit.<\/p>\n\n\n\n
