A2 steel is knows as air harden steel while O1 steel is oil harden steel. Here we briefly compare this two tool steel grades as follows. A2 tool steel belongs to A-Group in ASTM A681, which have high hardenability and may be hardened in air. O1 tool steel belongs to O-Group in A681 standard, which must be hardened by quenching in oil.
EN9 vs EN19 Steel: both belong to BS 970 standard. but en9 steel is carbon steel while en19 steel is alloy steel. you have the chemical composition properties. Check for more details now.
As you may know, in steel industry, there must be some dimension and sizes for one product or a project. And for each size of product, there will be some standard and tolerance requirements. In this post, we share the different round steel bar tolerance requirements between BS 970-3 and ISO 286-2 standard, for cold drawn, turned and precision round steel bar.
If you are in steel industry, have you ever notice what all those chemical composition listed on a steel materials test report really mean? Here we list 21 chemical elements which effect steel properties. You can check for details of each chemical elements and effects on steel materials mechanical properties.
There are Six groups of tool steel: water-hardening, cold-work tool steel, shock-resisting, high-speed, hot-work tool steel, and special purpose/plastic mold tool steel. The choice of group to select depends on, cost, working temperature, required surface hardness, strength, shock resistance, and toughness requirements.
When choosing a steel materials for a job, it is important to know the difference between the different types of steel grades, steel process available, how it is used and the advantages of including it in your industrial or construction project. This post will explain the differences between hot rolled steel, cold rolled steel, forged steel and cast steel, discuss the advantages and applications of each.
There are so many different standards institutes and organizations worldwide. Every country will have their own standards system by national organization or sectors. We list 9 common international known standards institutes and organizations, AISI, ASTM, DIN, BS, ANSI, JIS, AFNOR and AS, which are widely used worldwide.
You may also don't know SAE and AISI different steel grades and names. This post will solve some confusion and you will know what's the difference and how to check SAE and AISI steel grades.
You can check the compare in three common hot works tool steel, H13 vs 1.2344 vs SKD61. I compare the chemical composition, hardness, different standard scope and applications. All those three hot work tool steel are widely used in worldwide and you can even regard them equal to each other, although there are small difference in chemical and properties.
