1045 vs 1055 hardening - Eng-Tips Engineering Forums

Dec 17, 2007 · The first two digits of the steel grade (10) indicate a plain carbon steel (no alloying elements other than a small amount of Manganese). The last tow digits (45 or 55) list the aim carbon content (that is 0.45% and 0.55%). Carbon has a very strong effect on the hardness of the steel 8Cr13MoV BladeForumsMar 22, 2008 · In CATRA lab tests at Spyderco, 8Cr13MoV edge retention was in the area of AUS-8. The steel held thin edge angles quite well and would perform at a fairly hard Rc. Corrosion resistance was not as good as AUS-8. AUS-8 will get sharper as the steel has a very homogenous grain structure and the foundry, Aichi in Japan, does a very good job at

AISI/SAE Steel and Alloy - Designation System

SAE - Society of Automotive Engineers; Alloy steels and carbon steels can be designated with specific grades by a four-digit AISE/SAE numerical index system. The system is based on the chemical compositions of the steels and alloys. Example AISI/SAE No. 1020. the first digit indicates that this is plain carbon steel.

AUS 8 steel BladeForumsJun 05, 2009 · Take an edge:5 Takes a sweet razor edge Hold an edge:3 440C, VG10, AUS10 hold an edge better. Not only in my manila rope cutting tests, but enough better so that I notice the difference in everyday use. ATS34 / 154CM holds an edge better than those. I'm told that S30V and D2 hold an edge better than ATS34 and 154CM

Best Knife Steel Comparison - Steel Charts & Guide Blade HQ

CPM-154 is an excellent EDC blade steel with above average edge retention, corrosion resistance, and ease of sharpening. 154CM. Both great steels, CPM-154 benefits from a powdered metallurgy and is finer grained than 154CM. Powdered steels are more consistent, have better edge retention, and improve toughness due to a lack of inclusions.

EngineeringClicks - The No.1 Mechanical Design Engineering

In Taiwan, a huge 140 meter (459 feet) bridge collapsed in October of 2019, the event is known as the Taiwan Bridge Collapse. The oil tanker that was traversing the bridge at the time fell into the water and caused a fire when it struck three fishing boats that were Metal and Metallurgy engineering Forum - Eng-TipsProfessional forum and technical support for engineers for Metal and Metallurgy engineering.

Steel Standards - ASTM International

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. The Pitfalls of Using Gauge to Compare - Quality EdgeA few resource s are ava ilable for comparing how thickness relates to gauge in the sheet metal category, such as the gauge comparison from the Engineers Edge. Looking at the decimal thickness enables more precise (and sometimes surprising) comparisons. For example, TruCedar siding is G60 galvanized steel with a thickness of .016.

What is K390 Comparable to? - Spyderco Forums

Dec 10, 2016 · K390 is the closest to A11, 10v or K294. S90V is the closest stainless steel to K390 that I am aware of. K390 is a very wear resistant steel and should fall into a similar performance class as S110V but composition wise the S110V has a lot more in it and it is stainless. Short answer, it is the European equivalent of 10v/A11. Wood beam equivilant in steel? - Fine HomebuildingOct 04, 2006 · In my experience, steel is significantly smaller and roughly equal in cost to glulams or other engineered beams. Steel will be smaller and more expensive than your sawn-lumber options, and you will find that you have several options in terms of beam size and weight, i.e. there will probably be a lighter-gauge 8" web and a heavier-gauge 6" web that would both work.
